Litter Glitter helps make your cat more affectionate and loving by creating a calming olfactory environment in and around the litter box, turning a stressful chore that your cat does up to five times a day into an enjoyable experience.

Specifically, Litter Glitter prevents urine smell at the source and provides a faint, scent of pure cinnamon bark, which cats find calming. Over time, that improved litter box experience translates into a more loving, appreciative cat.

Also, with Litter Glitter, your cat litter might last twice as long, and you won't have to change out the entire litter box as often.

Feline urine odor is driven primarily by ammonia and by the thiol compound 3-mercapto-3-methylbutan-1-ol. Freshly voided urine contains negligible amounts of ammonia or 3-mercapto-3-methylbutan-1-ol and is therefore essentially odorless. Instead, fresh urine contains large amounts of urea and felinine, which later break down into ammonia and 3-mercapto-3-methylbutan-1-ol after the urine sits in the litter box and ferments.

The enzyme urease converts urea into ammonia, while the enzyme cysteine-conjugate β-lyase converts felinine into 3-mercapto-3-methylbutan-1-ol (Figure 1). These enzymes are produced by bacteria in the litter box, introduced from feces and from the surrounding litter box environment. These enzymatic reactions generate the strong, persistent odor associated with litter boxes and contribute to aversive cat behaviors and inappropriate elimination.

Litter Glitter is designed to inhibit both urease and cysteine-conjugate β-lyase, preventing the formation of ammonia and 3-mercapto-3-methylbutan-1-ol. By blocking both enzymes, Litter Glitter prevents the initial formation of feline urine odor before it occurs.

Figure 1. Urease converts urea into ammonia, and cysteine-conjugate β-lyase converts felinine into 3-mercapto-3-methylbutan-1-ol. These two bacterial reactions are responsible for the strong odor that develops after urine sits in the litter box.

The cinnamon bark may also directly reduce urine odor by reducing the concentration of thiols responsible for urine odor. Thiols can readily react with unsaturated aldehydes at room temperature [1]. We believe the cinnamaldehyde and 2-methoxy cinnamaldehyde in cinnamon bark react with thiols, transforming them into non-odorous compounds to alleviate urine odor (Figure 2). 

When cinnamon bark powder is mixed with boric acid under high-speed conditions, the mixture’s ability to prevent ammonia formation increases to more than double the inhibitory effect of either component alone.

Figure 2. Cinnamaldehyde reacts with a thiol, such as the released odor-causing 3-mercapto-3-methylbutan-1-ol to transform the thiol into a less obnoxious-smelling molecule.

Other odor-control approaches for litter boxes rely on perfumes that attempt to mask odor or adsorbents that try to capture odor after it has already formed. Masking or absorbing odor is a less effective strategy for true odor control. Litter Glitter stops urine odor at the molecular level, before it starts.

Pure cinnamon bark offers two benefits: it calms cats and, as described above, prevents odors.

Cinnamon bark contains compounds that may influence feline behavior—similar to how some cats react to scents like catnip or silvervine. For example, up to 70% of cats find catnip stimulating, while cats perceive cinnamon bark as calming.

Some zoos have studied the use of cinnamon bark to reduce anxiety. In studies, hay balls filled with cinnamon lowered anxiety—measured by repetitive pacing—in cheetahs and tigers more than hay balls filled with catnip [2, 3]. The cheetahs and tigers also interacted more with the cinnamon hay balls than with the catnip ones [2]. Cats, including lynx, jaguars, and oncillas, seem to find the scent of cinnamon bark calming.

Litter Glitter introduces a new scent into your cat’s most private space at a time when your cat is most alert—during bathroom use. Litter Glitter is designed to help your cat associate the litter box with calmness rather than alertness and stress. This passive conditioning creates a more peaceful experience for your cat, leading to a more confident, loving feline.

You won't find pure cinnamon bark in any other cat litter additive.

Poop smells. No matter what other products claim, there’s no way to completely block or absorb poop odor. To eliminate poop odor, you need to scoop it away. Adult cats poop once or twice a day.

That said, Litter Glitter can dramatically reduce poop odor by making your cat more likely to cover their poop. Because Litter Glitter keeps urine fresh and makes the box more attractive, it can encourage scratching and digging—making your cat more likely to cover poop until you have time to scoop.

Litter Glitter also helps keep your whole home cleaner. Bacteria, mold, and fungi can use ammonia and organic waste from decaying urine to grow. An unclean litter box can also attract insects like flies, gnats, ants, and roaches.

When your cat licks its paws or cuddles up with you on your bed or sofa, Litter Glitter gives you extra peace of mind that you’ve helped keep your cat and its environment as clean as possible.

By using Litter Glitter, you help support your whole household’s well-being.

Summary: Across multiple independent studies in domestic cats, lynxes, oncillas, cheetahs, and tigers, cinnamon is consistently attractive or calming.

Preference testing performed by the makers of Litter Glitter with domestic cats showed that, when given a choice, cats prefer a litter box containing Litter Glitter, made with pure cinnamon bark, over an otherwise identical box without it (US Patent 19/017,341). Studies in larger wild cat species echo this pattern: cinnamon increases exploratory interest, promotes object play, and reduces stress-related behaviors such as repetitive pacing.

Taken together, the evidence suggests that cinnamon bark has distinctive behavioral effects in cats, supporting its use as the active ingredient in Litter Glitter to relieve litter box-related stress.

Published Studies in Felids

Cinnamon Attracts Lynxes: This study involved two male and one female adult lynx in a half-acre open enclosure [4]. The cats’ movements were recorded with RFID chips. Either catnip, valerian, cinnamon, or nothing as a control was applied to a branch. The branch was then tied to the base of a tree. Each day, the scent was rotated by replacing the branch. The study lasted 45 days. Over this period, the three cats visited the tree a total of 45 times. The cats spent about six times as much time at the tree when cinnamon or catnip was used compared with valerian or no scent at all (Figure 1). The cats also spent more time rubbing on the tree when cinnamon was used, relative to nothing or valerian. 

Figure 1. Average amount of time the lynxes spent visiting a tree covered with either catnip, valerian, cinnamon, or nothing as a control.

Cinnamon Reduces Repetitive Pacing in Northern Tiger Cats: This study investigated how exposure to cinnamon or catnip influenced repetitive pacing in 12 oncilla cats (Leopardus tigrinus)[3]. Baseline pacing was monitored for three days. Then 1 g of cinnamon was sprinkled on wood chips daily for three days, and pacing was recorded again. After cinnamon was removed, catnip was added for an additional three days. Cinnamon reduced pacing by approximately 38% relative to baseline or catnip (Figure 2). In contrast, catnip did not meaningfully reduce pacing.

Figure 2. Average number of times each cat was seen pacing when either catnip or cinnamon was added to their dens.

Cinnamon Attracts Cheetahs, and Tigers: Eight cats (six cheetahs and two Sumatran tigers) were observed to see whether cinnamon or catnip changed how much they interacted with a toy hay ball about the size of a basketball [2]. Each day for seven consecutive days, each animal was given either a hay ball with no scent, a hay ball with catnip, or a hay ball with cinnamon. After the hay ball was introduced, the animals were observed for one hour, and the amount of time each animal spent interacting with the hay ball was recorded. A seven-day interval was given between each hay ball condition (Figure 3). Cinnamon increased the amount of time the cats spent with the hay ball by up to 43%, compared with the unscented and catnip hay balls. The cinnamon hay balls also reduced pacing by 37%, compared with unscented hay balls.

Figure 3. Average amount of time each cat played with a toy hay ball during the one-hour observation period.

Conclusion

Across studies in multiple felid species, cinnamon has been repeatedly associated with greater engagement with enrichment objects and reduction in stress-associated pacing behaviors. These findings are consistent with preference testing conducted by the makers of Litter Glitter in domestic cats, in which cats preferred the litter box containing Litter Glitter over an otherwise identical box without it.

A BETTER LITTER BOX EXPERIENCE CREATES A CALMER, MORE AFFECTIONATE CAT

Litter Glitter is designed to make cats more loving and affectionate over time by improving the single most stressful place in their daily life: the litter box.

Cats are not distant or “mean”. Cats become less social when they feel stressed, uncertain, or uncomfortable. The litter box can be one of the most consistent drivers of that stress because cats are biologically vulnerable while eliminating, and are highly sensitive to smell, cleanliness, and negative associations with the litter box.

Litter Glitter improves the litter box environment in two ways:

1. It makes the litter box more inviting to cats using pure cinnamon bark, which has been observed across multiple studies to increase engagement and reduce stress-related behaviors in felines.

2. It helps prevent urine odor from forming, reducing a major source of litter box aversion.

Litter Glitter is supported by preference testing: Cats were offered two identical litter boxes: one treated with Litter Glitter and one untreated. Litter box preference was assessed by the amount of waste in each litter box. When given a choice, cats chose litter boxes containing Litter Glitter over identical litter boxes without it.

The combination of calmness around the litter box and reduced odor, is why Litter Glitter is expected to work. Over time, when the litter box becomes a calmer and cleaner experience, many cats become more confident and socially engaged in the home — which owners experience as a more loving cat.

CATS' ATTITUDES REFLECT THEIR OWNERS AND THEIR ENVIRONMENT

Besides genetics, a cat’s behavior depends heavily on its owner: how the cat is treated and cared for. Many studies support this link. Cats that have a higher quality of life are reported to be more loving and affectionate. Owners who better understand cat behavior tend to share stronger bonds with their cats[5]. Owners who spend more time with their cats report having better-behaved cats [6]. In one study, the percentage of cats given a high quality of life (18%) was similar to the percentage of cats with excellent behavior (16%) [7]. This study, along with several others, concluded that cat behavior is strongly influenced by the owner and the cat’s environment [7]. 

Stress and anxiety can cause various negative behaviors in cats, such as hiding, aggression, aloofness, scratching, and avoiding play [8-11]. Even things you might not think of as stressful—such as feeding your cat at a different time, or not talking to or petting your cat—can raise cortisol levels, decrease social interactions, and lead to withdrawal [9-11]. In one study, 75% of cats with a consistent routine displayed friendly behavior toward a stranger (approaching, rubbing against their leg, making direct eye contact, holding their tail upright, and rolling over). Conversely, only 10% of cats with inconsistent routines—which can cause stress—showed friendly behavior [12]. 

STRESS AND ANXIETY REDUCE SOCIAL BEHAVIOR AND BONDING

Stress and anxiety lower confidence, which reduces a cat’s ability to bond. High stress and low confidence decrease social behaviors like rubbing, seeking closeness, lying on the lap, purring, and voluntary interactions with humans, while increasing withdrawal. The key to a more loving, affectionate cat is simple: provide the best care possible, and your cat will reward you with its love and affection. 

THE LITTER BOX IS A HIGH-STRESS ENVIRONMENT

Cats attach a lot of stress and anxiety to the litter box. In the wild, cats face threats from coyotes, foxes, hawks, owls, snakes, dogs, bobcats, cougars, and raccoons. As a result, cats are on high alert and ready to flee at the slightest sign of danger—hence the term “scaredy-cat.” Their genetics predispose them to anxiety. When cats use the bathroom, they are most vulnerable to attack. Evolution has made them naturally alert and anxious during elimination. Cats can’t help this. 

Some breeds experience more litter box anxiety than others, which can contribute to more frequent house soiling [13]. In one study, Bengal cats were found to be the most skittish and to have the most house soiling, while Siberian and Neva Masquerade cats were found to be the least skittish and to have the least house soiling [13]. 

WHAT LITTER BOX STRESS LOOKS LIKE IN REAL LIFE

Cats use the litter box up to five times a day. The litter box can be either a source of stress for your cat or an opportunity to show your cat you care. When given a choice, cats will choose the litter box setup they like best. Cats show up to 39 different behaviors when using the litter box [14]. From these behaviors, the science is clear when a cat is frustrated or happy with its litter box. 

Eliminating outside the box is just one result of litter box–related stress. Some cats might continue to use a stressful litter box [14], but it still affects their comfort and ability to bond. Signs of litter box stress include hesitating at the entrance, perching on the edge, reducing digging or covering, minimizing contact with the litter, or quickly leaving the box after urination or defecation. Some cats may even “hold it in” to avoid using the litter box as much as possible [14]. 

CATS CAN HIT THEIR BREAKING POINT

A bad experience can worsen a cat’s natural litter box–related anxiety and reduce its willingness to use the box. For example, a cat that has had an episode of constipation or diarrhea may remember it so strongly that it may refuse to use the litter box because it has associated the box with a negative event. If a cat has been frightened by a loud noise while going to the bathroom, it may develop more anxiety around elimination. When cats are forced to use a smelly, soiled litter box, they can also quickly develop a negative association with the litter box. 

A cat who is tolerating a dirty litter box—or a litter box in a difficult-to-access or noisy location—may be pushed past its threshold and stop using it if anxiety levels increase further, from anything as minor as new people in the home to a major household renovation[15]. Otherwise healthy cats that refuse to use the litter box are sometimes prescribed anti-anxiety drugs such as Valium, Xanax, and Prozac to reduce litter box anxiety [16] 

HOW LITTER GLITTER WORKS

Litter Glitter is designed to provide the best possible litter box experience by reducing stress and odor. Having a clean-smelling litter box isn’t enough. Since cats are naturally stressed when using the litter box, Litter Glitter is formulated with cinnamon, which has a calming effect on cats. With Litter Glitter, cats feel calmer when using the litter box. Additionally, because urine odor can make the litter box experience worse, Litter Glitter helps prevent urine odor from developing. 

SIGNS YOUR CAT IS HAPPIER WITH LITTER GLITTER

When a cat is happy with its litter box, you will notice. Your cat may cover its waste more consistently, use the litter box more often, and exit the litter box with confidence, tail up. Your cat might even start leaving its toys in the litter box. 

THE BOTTOM LINE

When daily litter box stress is reduced, and the litter box is turned into one of your cat’s most frequently visited places in the home, cats can become more relaxed. You get a calmer, more confident cat that is more likely to seek closeness, rubbing, purring, and affectionate contact with the people in its household.

Executive Summary: This risk assessment evaluates the potential for chronic repeat-dose exposure to active ingredients in Litter Glitter—specifically boric acid, copper sulfate, and cinnamon bark powder—and assesses the risk of routine product use in approaching toxicity thresholds in feline subjects.

The assessment employs conservative exposure modeling, including worst-case scenarios of incidental oral ingestion through paw-licking behavior, and benchmarks plausible daily exposures against established repeat-dose toxicity parameters (No Observed Adverse Effect Level/Lowest Observed Adverse Effect Level) derived from standard mammalian toxicology studies. These values have been scaled to feline physiology using body surface area (BSA) allometric scaling methods.

Key Findings: Estimated exposures from normal product use fall several orders of magnitude below cat-equivalent NOAEL and LOAEL thresholds for both boric acid and copper sulfate, demonstrating substantial margins of safety under realistic usage conditions. Cinnamon bark powder, given its extensive history of dietary consumption in both human and veterinary applications, including long-term livestock feeding studies at elevated dietary inclusion levels, is not anticipated to present toxicity concerns at the incidental exposure levels associated with litter box use.

Consequently, this quantitative risk assessment prioritizes boric acid and copper sulfate, for which well-defined repeat-dose toxicity benchmarks enable rigorous margin-of-safety calculations.

1. Chronic Repeat-Dose Toxicity Assessment
1.1 Exposure Pathway

Feline subjects may engage in paw-licking behavior following litter box use, potentially facilitating transfer of boric acid from Litter Glitter to oral mucosa for subsequent ingestion. While normal ambulation and grooming behaviors would be expected to remove the majority of any residual powder from paw surfaces, incidental ingestion remains a plausible exposure route requiring toxicological evaluation.

1.2 Toxicological Benchmarks boric acid

To assess the potential for adverse health effects from chronic boric acid exposure via regular Litter Glitter use, we derived feline-specific NOAEL and LOAEL values through allometric scaling of chronic repeat-dose toxicity data using body surface area methodology[17]. This assessment is based on the three comprehensive reports for boric acid exposure [18-20].

Table 1 presents chronic repeat-dose toxicity data for boric acid in rats and dogs along with corresponding BSA-adjusted NOAEL and LOAEL values for feline subjects.

In rat studies, the chronic NOAEL for orally administered boric acid was established at 100 mg/kg/day over a two-year period, with a LOAEL of 335 mg/kg/day. In canine studies, the chronic NOAEL was determined to be 50 mg/kg/day over two years, with a LOAEL of 167 mg/kg/day. In both species, observed adverse effects were primarily testicular in nature. The consistency of these values across species provides robust confidence in the benchmark doses.

Following BSA-based allometric scaling for feline subjects, the rat-derived cat-equivalent NOAEL is 46 mg/kg/day with a cat-equivalent LOAEL of 155 mg/kg/day. The dog-derived cat-equivalent NOAEL is 77 mg/kg/day with a cat-equivalent LOAEL of 257 mg/kg/day.

1.3 Margin of Safety Analysis

For a typical 4 kg cat, these values correspond to absolute daily doses of approximately 184 mg/day (rat-based NOAEL) or 308 mg/day (dog-based NOAEL), with adverse effects observed at approximately 618 mg/day (rat-based LOAEL) or 1,028 mg/day (dog-based LOAEL).

These NOAEL values exceed the estimated boric acid exposure from normal Litter Glitter use (conservatively estimated at approximately 5 mg under extreme-case scenarios) by several orders of magnitude, thereby establishing a substantial margin of safety under realistic exposure conditions.

Table 1: NOAEL and LOAEL from Chronic Repeat-Dose Toxicity Studies of Boric Acid

All dose values are expressed as mg boric acid per kg body weight per day unless otherwise stated.
Cat-equivalent values are body-surface-area (BSA) adjusted from rat→cat and dog→cat.
Cat daily values assume a 4 kg cat.

2. Chronic Repeat-Dose Toxicity Assessment: Copper Sulfate
2.1 Toxicological Evaluation

A parallel risk assessment was conducted for copper sulfate, an additional active ingredient in Litter Glitter. The assessment was based on the three comprehensive reports for copper sulfate exposure [21, 22].

Utilizing repeat-dose oral toxicity data and BSA-based allometric scaling methodology, the cat-equivalent NOAEL and LOAEL are estimated at 30 mg/kg/day and 61 mg/kg/day, respectively.

2.2 Margin of Safety Analysis

For a typical 4 kg cat, these values translate to approximately 121 mg/day (NOAEL) and 242 mg/day (LOAEL). These thresholds exceed the maximum conceivable copper sulfate ingestion from normal Litter Glitter use—conservatively estimated at <1 mg/day—by several orders of magnitude. This substantial margin of safety indicates negligible risk under realistic exposure scenarios.

Table 2: NOAEL and LOAEL from Repeat-Dose Toxicity Studies of Copper Sulfate

All dose values are expressed as mg copper sulfate pentahydrate (CuSO₄·5H₂O) per kg body weight per day unless otherwise stated.
Cat-equivalent values are body-surface-area (BSA) adjusted from rat to cat.
Daily cat values assume a 4 kg cat.

3. Chronic Exposure Assessment: Cinnamon Bark Powder
3.1 Safety Profile

Cinnamon bark powder, an ingredient in Litter Glitter, possesses an extensive history of safe use as a natural food and feed ingredient across human and veterinary applications. Long-term animal feeding studies document repeated dietary supplementation with cinnamon powder at elevated inclusion levels without systemic toxicity[23-25].

3.2 Supporting Evidence

Published veterinary nutrition literature, including poultry feed studies, reports the incorporation of cinnamon powder at concentrations up to 10% of total feed in broiler diets. Observed biological effects were limited to beneficial modulation of gut microbiota (including increased Enterococcus and Lactobacillus populations and reduced Campylobacter and Escherichia coli colonization) rather than systemic toxicity findings. This body of evidence, demonstrating tolerance of high-level dietary cinnamon exposure in animal subjects, supports the safety profile of cinnamon powder as a feed ingredient.

Given this established safety record and the absence of defined repeat-dose toxicity benchmarks comparable to those available for boric acid and copper sulfate, the quantitative safety analysis prioritizes boric acid and copper sulfate—the ingredients for which clearly defined NOAEL/LOAEL values enable conservative margin-of-safety calculations.

4. Alternative Routes of Exposure: Dermal, Inhalation, and Ocular Contact
4.1 Overview

In addition to incidental oral ingestion via paw-licking behavior, Litter Glitter could theoretically contact feline subjects through alternative exposure routes during normal litter box use, including dermal contact with paw pads, inhalation of airborne particulate matter, and incidental ocular contact. These routes are anticipated to present negligible risk given that the product functions as a minor additive dispersed within the litter matrix, and exposure duration is characteristically brief and intermittent.

4.2 Dermal Exposure Assessment

Exposure Characteristics: Feline subjects will experience direct dermal contact with cat litter during normal usage patterns, primarily through paw pad contact. The constituents of Litter Glitter are anhydrous particulate materials not expected to produce systemic toxicity via dermal absorption pathways. Consequently, potential dermal risk is confined to localized irritation responses.

Ingredient-Specific Considerations: Boric acid does not exhibit dermal irritant classification in standardized dermal irritation protocols. Cinnamon bark powder possesses widespread application in food and feed industries without documented dermal hazard concerns at low-level exposures. While copper sulfate can manifest irritant properties at elevated concentrations, the context of Litter Glitter use involves substantial dilution within the litter substrate, resulting in minimal exposure of brief duration.

Risk Characterization: Dermal irritation to paw pad epithelium is considered improbable under normal usage conditions.

4.3 Inhalation Exposure Assessment

Exposure Pathway: Fine particulate matter may become aerosolized during product dispensing, mixing operations, or active substrate excavation by feline subjects. Inhalation risk relates primarily to respiratory tract irritation from particulate deposition rather than systemic toxicological endpoints.

Exposure Mitigation: Litter Glitter is formulated for incorporation into existing litter substrates, which substantially attenuates the potential for free airborne powder following initial application. Under typical usage scenarios, airborne concentrations are expected to remain minimal and transient in nature.

Precautionary Measures: As a prudent measure, end users may apply the product gradually to minimize dust generation, avoid creating concentrated aerosol clouds during application, and permit adequate settling time post-mixing before allowing feline access to the litter box.

Risk Characterization: Inhalation exposure under normal use conditions is anticipated to be low and unlikely to produce adverse respiratory effects.

4.4 Ocular Exposure Assessment

Exposure Characteristics: Any particulate matter, including conventional litter dust, possesses the potential to cause transient ocular irritation upon contact with corneal or conjunctival surfaces. While boric acid finds routine application in ophthalmic preparations at low aqueous concentrations, incidental exposure to anhydrous particulate material may still elicit mild, temporary irritation through mechanical mechanisms.

Risk Characterization: Given the minimal dust generation anticipated once the product is integrated into the litter substrate, the probability of ocular irritation is considered low. Should ocular irritation occur, effects would be expected to be transient and comparable in nature to typical litter dust exposure.

4.5 Summary of Alternative Exposure Routes

Dermal, inhalation, and ocular exposures are projected to occur at low frequency and intensity with intermittent exposure patterns. Associated risk is predominantly confined to potential mild, localized irritation rather than systemic toxicological effects. The product's intended application methodology—incorporation into litter substrate rather than direct application to feline subjects—further diminishes the likelihood of significant exposure through these alternative routes.

5. Conclusion

This comprehensive risk assessment demonstrates that Litter Glitter, when used as directed, presents minimal toxicological risk to feline subjects. Conservative exposure modeling indicates that potential ingestion of active ingredients through incidental paw-licking behavior results in exposures that fall well below established toxicity thresholds, with substantial margins of safety for all components. Alternative exposure routes including dermal contact, inhalation, and ocular exposure present primarily localized, transient irritation potential rather than systemic toxicity concerns. These findings collectively support the safety profile of Litter Glitter for routine use in feline litter management applications.

Cinnamon bark may have a calming effect. Cinnamon bark has been used in households alongside cats for a long time. In fact, some zoos use cinnamon bark to calm big cats.

Let’s be clear: Litter Glitter doesn’t contain cinnamon oil. Cinnamon oil may bother cats’ paws and skin. The pure cinnamon tree bark in Litter Glitter is different from cinnamon oil. People mix them up: cinnamon oil can irritate cats, but cinnamon tree bark in Litter Glitter is typically non-irritating.

Litter Glitter was designed with the understanding that cats lick their paws. If they do so shortly after using the litter box, whatever is in the litter box might end up in the cat’s mouth. Further, when cats scratch in the litter box, dust might be generated that your cat could inhale. We are also aware that whatever is in the litter box may get on your cat’s paws, skin, and fur and be absorbed through the skin.

For these reasons, Litter Glitter is made with ingredients selected for litter box use. Exposure via the routes above is not expected to cause harm when used as directed.

If your cat has pica and eats its litter, don’t add anything—including Litter Glitter—to your cat’s litter. Observe your cat. Pica is uncommon and usually noticeable. It is possible that a small percentage of cats might be allergic to an ingredient in Litter Glitter. We have not yet met a cat that is.

Whenever you introduce something new to your cat, monitor your cat for several days. If you see any negative changes, stop using the product.

The ASPCA also states that cinnamon is non-toxic to cats.

Litter Glitter blocks odors on a molecular level, halting the transformation of fresh urine into foul-smelling sulfur and pungent ammonia. In contrast, other products attempt to mask, trap, or absorb odors after they have already formed.

Litter Glitter blocks odors and calms cats at the same time. Cats use the litter box multiple times a day. Providing a calm, stress-free bathroom experience is essential to your cat’s well-being.

Also, Litter Glitter blocks odors on a molecular level, halting the transformation of fresh urine into foul-smelling sulfur and pungent ammonia. In contrast, other products attempt to mask, trap, or absorb odors after they have already formed.

No. We tested Litter Glitter in small 8x8-foot rooms and could not smell the cinnamon. Your home will not smell like cinnamon.

Litter Glitter has a mild smell. It uses ground-up tree bark from the cinnamon tree, which is typically non-irritating. It doesn’t contain artificial cinnamon, which can be irritating. Litter Glitter won’t bother most cats. It uses ground-up tree bark from the cinnamon tree, which is typically non-irritating. Litter Glitter is free of artificial cinnamon, which can be irritating.

It won’t work the same. Litter Glitter has other ingredients in it. And we use high-energy mixing to create a cohesive power. For the amount of pure cinnamon bark you get in Litter Glitter, it’s cheaper to buy Litter Glitter than cinnamon. We buy large quantities of cinnamon bark, so you can’t beat our price.

Yes. When introducing it to your cat, start with a small amount to observe their reaction. All ingredients have a long history of use. In fact, most cats simply love Litter Glitter.

Mild. Your home will not smell like cinnamon. Cats are sensitive to smells and like routine. We designed the product with this in mind.

Litter Glitter uses ground-up tree bark from the cinnamon tree, which is typically non-irritating. Litter Glitter is free of artificial cinnamon, which can be irritating.

Use within a year. Once opened, the cinnamon bark becomes weaker over time.

Any gravel litter works best with Litter Glitter. At Team Glitter, we prefer non-clumping gravel cat litter because it is excellent at fighting odors. Most cats love non-clumping gravel cat litter, and it is affordable.

Litter Glitter also works exceptionally well for organic cat litter, including wood, grass pellets, corn, coconut husk, rice husk, wheat, corn, walnut husk, and paper. Organic cat litter needs to be changed more often than clay litter. Using Litter Glitter will make your organic cat litter last about twice as long.

Poop smells. No matter what other products claim, there is no way to completely block or absorb poop odor. To eliminate poop odor, you need to scoop it away.

That said, Litter Glitter can help reduce poop odor by making your cat more likely to cover their poop. Because Litter Glitter keeps urine fresh and attracts cats to the litter box, it encourages your cat to scratch and dig, making them more likely to cover up their poop—reducing its smell until you have time to scoop it.

No. Don’t do it. Litter Glitter is designed for cat litter only.

All the ingredients in Litter Glitter have been well-known for a long time and have a long history of use.

Possible means of exposure: Litter Glitter was designed with the understanding that cats lick their paws. If they do so shortly after using the litter box, whatever is in the litter box might end up in the cat’s mouth. As the cat scratches in the litter, dust might be generated that your cat could inhale. Whatever is in the litter box may get on your cat’s paws, skin, and fur and be absorbed through the skin.

For these reasons, Litter Glitter is made with ingredients selected for litter box use. Exposure via the routes above is not expected to cause harm when used as directed.

Another thing: if your cat has pica and eats its litter, don’t add anything—including Litter Glitter—to your cat’s litter. Observe your cat. Pica is uncommon and usually noticeable.

Remember, whenever you introduce something new, you should monitor your cat for several days for any changes. A small percentage of cats may be allergic to an ingredient in Litter Glitter.

Use within a year. Once opened, the cinnamon bark becomes weaker over time.

Reseal the bag and store in cool, dry place. Keep out of reach of children.

Litter Glitter Ingredients: Pure cinnamon bark, naturally derived minerals (boric acid, copper sulfate).

Boric Acid: The boric acid in Litter Glitter stops the urea found in urine from turning into foul-smelling ammonia; it blocks urease enzymes that convert urea to ammonia. Pure

Pure Cinnamon Bark: Cinnamon bark makes the litter box more attractive for your cat. Some cats may respond to cinnamon bark's scent. The cinnamon bark in Litter Glitter also transforms the smelly sulfur compounds in poop and urine into non-odorous chemicals, thus eliminating their odor.

Copper Sulfate: Copper sulfate is a safe source of copper that’s added to pet food. The copper sulfate in Litter Glitter helps the cinnamon bark trap the smelly sulfur compounds in poop and urine to eliminate their odor.

No, Litter Glitter helps prevent odors from forming. Use it every time you change the cat litter for best results.

No. Litter Glitter is designed for cat litter boxes only.

How often you need to change your cat’s litter depends on the type of litter, how much litter you use, the size of your cat, and your cat’s diet.

Cheap, clay, non-clumping litter (which we like best) typically needs to be changed every two to three weeks when used by one adult cat.

When using Litter Glitter, you can easily go 4 to 8 weeks. You may never smell odors after scooping away the poop. But it’s still important to change your cat litter occasionally, even if it’s only twice a year.

One customer told us that, with Litter Glitter and the cheapest non-clumping clay cat litter they could find, they changed the cat litter out every six months. They only changed it because the cat litter started to deteriorate and turn to dust.

The amount of Litter Glitter you need depends on factors like the type of litter, the quantity you use, your cat’s size, and its diet. We suggest, after testing a small amount to see how your cat likes it, starting with two full scoops in a standard litter box. Begin by adding Litter Glitter to a freshly cleaned litter box with new cat litter for optimal results. Litter Glitter helps prevent new odors from forming, so it’s best to start fresh.

1.  Add 2 scoops of Litter Glitter to the bottom of a clean litter box.
2.  Add cat litter as normally done.
3.  Mix cat litter with a cat litter scoop to coat the cat litter with Litter Glitter.
4.  Remove poop as normally done.
5.  At least once a week, gently mix the cat litter with the cat litter scoop to allow urine to dry. Mix even when using clumping litter. Clumping litter, when wet, can get stuck to the bottom of the litter box and begin to rot. Turning the litter prevents this and keeps the box smelling fresh.

Yes, Litter Glitter works with clumping litter. The issue with clumping litter is that clumps of urine-soaked cat litter sink to the bottom of the litter box. In just a few days, these urine-soaked clumps start to smell. Due to these urine-soaked clumps, many non-clumping cat litter brands suggest changing the litter every month.
