Why Do Cats Eat Cat Litter? Common Causes and Solutions to Litter Eating in Cats
Have you ever seen a cat eat cat litter? Why do cats seem to enjoy eating something that has no nutritional value and can even be dangerous? There are many reasons why cats might eat cat litter. It's important to understand these reasons so you can address the problem and keep your cat safe.
Why Do Cats Eat Cat Litter?
Here are some common reasons why cats eat cat litter:
1. Curiosity
Kittens are naturally curious and like to explore the world around them. Cat litter can be a new and exciting object for them to taste. This behavior is most common in kittens under 3 months old and is less common in older cats.
2. Attraction to Scent
Some types of cat litter, like tofu litter or soy litter, are made from plant materials and have a distinctive scent. Some manufacturers also add fragrances, making the litter smell even more appealing to cats. These scents can trigger a cat's appetite, especially kittens who are prone to licking and accidentally ingesting things.
3. Anemia
In humans, eating dirt (mainly clay/bentonite) is often associated with anemia, iron deficiency, and hypokalemia. This same phenomenon has been observed in cats. A case report published in the Journal of Veterinary and Human Toxicology in 1996 documented a 2.5-year-old cat that ingested a large amount of bentonite. Examination revealed that the cat suffered from anemia, hypokalemia, and symptoms also common in humans, such as muscle weakness and dehydration.
4. Nutritional Deficiencies
When a cat doesn't get enough nutrients from its diet, it may start to eat non-food items. This is called pica. A lack of vitamins A, B1 (thiamine), magnesium, sodium, and/or taurine can all contribute to pica. The minerals found in cat litter (bentonite, silica) can attract cats, making them think they can supplement their diet.
5. Other Diseases and Health Problems
Eating cat litter can also be a sign of kidney disease and leukemia (which can also cause anemia). Some diseases, when accompanied by metabolic disorders, taste abnormalities, poor diet management, and nutrient deficiencies, can also trigger pica, leading cats to eat non-food items like cat litter. However, a diagnosis of pica requires repeated episodes of eating non-food items. If a cat (especially a kitten) only occasionally eats cat litter, it could be due to:
6. Boredom
Especially in households with fine bentonite clay litter, cats who enjoy playing in the litter box may occasionally eat a few grains of litter. This could be considered "trying a new flavor," but without intervention, this behavior could develop into a habit and lead to problems.
What Are the Dangers of Eating Cat Litter?
If a cat accidentally eats a few grains of cat litter that get stuck on their paws, there's usually no need to worry. Bentonite clay and silica-based tofu litter don't get absorbed in the gastrointestinal tract and are excreted in the feces. Regular brand-name tofu litter undergoes testing for formaldehyde and mold, so ingesting small amounts is harmless. However, if a cat makes a habit of eating cat litter, long-term or excessive consumption can lead to serious problems!
1. Bentonite Toxicity
Can cats eat a little bit of litter every now and then and be okay? No. In both humans and cats, prolonged ingestion of bentonite has been linked to muscle pain, weakness, and lethargy. The case report published in the Journal of Veterinary and Human Toxicology also showed that the cat exhibited depression, ataxia, and heart murmurs. So even if the gastrointestinal tract can successfully excrete the litter, long-term consumption is a health hazard!
2. Large Ingestion of Gums and Plant-Based Components
Common tofu litter is made from corn flour, pea flour, tofu dregs, wheat straw, and other plant-based materials, bound together with tapioca starch, guar gum, and sometimes includes bentonite clay and odor control granules. The undigestible components are excreted in the feces, and while small amounts of the digestible components are harmless, plant-based materials are generally difficult for cats to digest. Similarly, small amounts of paper litter and pine litter are harmless, but large or habitual ingestion should be stopped. Avoid crystal litter altogether! Additionally, there are still some hidden dangers in the tofu litter market, so it is not recommended to let cats eat it.
3. Constipation, Even Requiring Emergency Surgery
Any type of cat litter, if ingested in large quantities, can clump together in the cat's intestines, impairing digestion and leading to loss of appetite, malnutrition, anemia, and dehydration. If the clump is too large to pass through the pelvis and causes a blockage, surgery may be needed to remove the foreign object, and in severe cases, the necrotic intestines may need to be removed. In 2009, Marina Michaels shared the story of her kitten's death from ingesting large amounts of bentonite (although she labeled the image as bladder stones).
Of course, besides avoiding cats from eating dirt, it's crucial to remember that if your cat regularly eats dirt, there may be other underlying health issues, and you should consult a vet for a thorough examination and treatment.
How to Stop a Cat from Eating Cat Litter
It's usually easy to notice when a cat suddenly starts eating large amounts of cat litter. However, long-term, small amounts of litter ingestion can be harder to detect. If your cat likes to play with cat litter, even digging and scratching it around the house, be aware of the possibility of accidental ingestion. Therefore, different causes of litter ingestion can manifest in different ways and require different solutions:
1. Find a "Toy" Substitute
If a cat, especially a kitten, eats cat litter because of boredom and a desire to play with it, consider buying new toys to distract the cat and guide it to interact with these "new toys," gradually making it forget about the "old food." If a kitten has a favorite toy or playmate, it will be more interested in playing than digging in the litter box and will have no interest in the litter.
2. Change the Type of Cat Litter
If a cat develops a taste for litter after a litter change or continues to play and eat it, try switching to a different type of litter, especially one that doesn't have a strong scent, which can also reduce the cat's desire to eat it. In case reports shared by vets, adult cats that ate bentonite clay litter stopped eating it when switched to tofu litter, while kittens that ate tofu litter stopped eating it when switched to bentonite clay.
3. Conduct a Health Checkup
If your cat has a long history of eating cat litter, you should first have a blood test done to check for anemia. Urine analysis and abdominal ultrasound can help determine kidney health. X-rays can help detect blockages caused by foreign objects. In addition, if you suspect that the cat may have nutrient deficiencies, leukemia, or other metabolic diseases, you will need to perform further tests to re-evaluate the cat's diet and find the cause for treatment.
4. Spend More Time Interacting with Your Cat and Exercise It
No matter if boredom or anxiety is the cause of pica, spending time playing with your cat can help distract it and reduce the occurrence of pica.
In conclusion, both humans and cats can eat dirt in small amounts without any serious consequences. However, if your cat shows a habit of eating dirt, please immediately intervene and stop it!
