Is cat litter toxic to cats if swallowed?

It is not ideal for a cat to eat its litter. Eating litter large quantities or on a regular basis can be harmful to its digestive tract. Also, it may point to an underlying deficiency in its diet. Given that, kittens will sometimes try to eat their litter and should be deterred from doing so. If your cat is eating cat litter, there are less harmful alternatives. Many kinds of cat litter not made of crystals or clay can be purchased at the grocery store. You can also use shredded paper towels. If your cat continues to eat its litter, you need to take it to the vet and find out what's going on.
