Cat’s eating litter? Here’s why and how to stop it

Sometimes, cats display strange behaviors when it comes to their litter boxes. It can be rather unpredictable. Other cats lie in litter boxes, while some eat their litter. If yours is in the latter group, you might be wondering, “Why is my cat eating litter?” When your cat has the urge to eat things they shouldn’t, it’s a common habit called “pica,” and unfortunately, eating litter is one form of this behavior that is a concern. However, there are some simple steps that can help you to stop your cat from doing this, and thereby normalize their behavior regarding litter. Generally, when cats or kittens are eating litter, it is either a sign of a physiological or behavioral problem.

Why is my cat eating litter?


Pica refers to an animal’s desire to eat nonfood items such as plastic, paper, string, sand, litter, and other bizarre things. Though it might also seem strange to you, your cat’s preference of bringing you pieces of animals that have been caught is actually not considered pica, but it can be unsettling. In most cases, pica occurs as part of either a behavioral or physiological problem.

In general, if you have noticed pica symptoms in your darling fur baby, make sure you contact a veterinarian as soon as possible. The pica may or may not be severe to be a sign of a problem. In most cases, only a medical professional can accurately diagnose whether or not the pica your cat is exhibiting is a sign of something serious or doing it simply out of boredom.


One of the main physiological reasons your cat is eating litter is because they are not able to produce enough red blood cells and hemoglobin. This condition, known as anemia, can be serious in our feline friend. If this is the cause, your cat is eating litter to try to get the vitamins, minerals, or fatty acids that it are otherwise missing from their diet. If your cat has very lightly colored, white, or bluish gums in their mouth, this is a strong indicator of anemia. If you suspect your cat is anemic, be sure to take it to the vet as quickly as you can.

Nutritional deficiencies

Nutritional deficiencies are common in many cats. Eating litter is actually a response to these nutritional shortfalls. Many commercial cat litters are made from clay and contain a wealth of minerals. Your cat senses this and tries to eat the litter to make up for what it is missing from their diet.

Other medical issues

This behavior could also be a sign of feline leukemia or kidney disease. To determine these diagnoses, your vet will need to analyze your cat’s complete blood count. An MRI or other imaging technique may be necessary. Again, if you are noticing that your cat is eating litter, don’t wait to bring them to a vet.


This is especially true for kittens who eat litter. Often, they don’t understand yet what it’s for, which is why it’s so important to use non-toxic, non-clumping litter for kittens as this will help prevent intestinal blockages. If your kitten is under three months of age, it’s not odd for them to eat litter. Keep an eye on your kitten and remove them from the litter box if they’re treating it as a snack, but they should eventually drop this habit/


In some cases, cats will eat their litter if they are not feeling stimulated enough. This could be a problem if your cat is not allowed to go outside. A bored cat will start to act out and do strange behaviors to amuse itself. This type of situation is possible in all pica cases, though only a veterinarian will be able to be absolutely sure about what is going on with your kitty.
