My cat started eating litter. Is this harmful and how can I stop it?

This can be a sign of pica, and it is bad for Mochi to do. It can cause an obstruction. Pica is a symptom of an underlying disease such as FIV, hyperthyroidism, anemia, feline leukemia, dental disease, diabetes, and others. I'd have her seen by a vet for this behavior. I hope this helps!

Clay or crystalline litter is not good if eaten as it can cause obstruction and some can be toxic if ingested. Place only a small scatter over newspaper in the tray until he learns how to use the tray more appropriately. Monitor for any vomiting or constipation

This can be a sign of a vitamin or mineral deficiency, anemia, kidney disease or feline leukemia in Miley, and I would have her seen by a vet for a physical exam, blood tests, and a urinalysis. These causes could also lead her to vomit and be quite skinny. Using these test, the vet can diagnose if she does have any of these conditions causing her symptoms, and can treat her for them. I would have her seen by a vet in the morning.

They will always ingest small amounts of litter that you cannot control as a small portion sticks to their feet or gets trapped in the fur and they groom it off to keep clean. It should be not be a large amount or anything that can cause harm. If he is eating large amounts, then the only option is to change types of litter. this will be trial and error to see what he will still use without eating. Look for a different scent or texture or different size particle to see if that helps

I would recommend that you have Gucci seen by your veterinarian. Eating non-food items such as litter can indicate an underlying medical problem such as parasites or nutritional deficiencies. Your veterinarian may recommend checking a stool sample or blood work to get a better idea what's going on. After it is determined that Gucci is healthy it is likely worth trying different types of litter such as cedar shavings or corn-based litter. It is very important that Gucci does not eat litter as this can cause an intestinal blockage.

Hi there and thank you for using Petco Pet Education Center, formerly Petcoach to address your concern. This sounds behavioral and will likely go away over time. However, in the meantime while the behavior is occurring, I would recommend switching the type of litter or even consider spraying bitter apple onto the litter itself. I hope this helps! Please let me know if you have any other questions or concerns and I would be more than happy to help you further.

I guess he just feels like it. This isn't a common problem among cats. In small amounts it is perfectly safe, but in larger amounts it could cause irritation to the GI tract or even an impaction. You might need to try another substrate for the litter box, such as shredded paper, packing peanuts, sand, a product called yesterday's news, etc.
