What causes a cat to scratch, eat litter, and jump after peeing?

Updated On September 23rd, 2025

Pet's info: Cat | Mixed Breed | Male | 60 lbs

This is my sister's cat Larry, about one or two years old. He's been scratching and biting himself since February, mainly on the tummy. He began eating the toilet granules about a week ago, and today even jumped right after peeing for no reason. Please, help.

Poor Larry. This scratching can be caused by fleas, mites, ringworm, or allergies. If he isn't up to date on his flea treatment, I can give you one for him. First, I would give him Capstar. It's a one time pill that starts killing fleas within 30 minutes. Then follow up with a spot on treatment, such as Advantage or Revolution. This is a treatment that has to be used once a month. You will also have to disinfect the environment. Wash his bedding in hot soapy water, and vacuum the furniture and carpet surfaces. You can use a spray to kill fleas in the house, such as Indorex, or a flea bomb would work well to kill the fleas in the home. If he is up to date on his flea treatment, I recommend taking him into the vet for an exam today or tomorrow. The vet can do blood tests, skin scrapings, and use a Wood's lamp to diagnose allergies, mites, and ringworm. Once the cause of the itching is found, the vet can prescribe the appropriate treatment. Eating kitty litter can be a sign of a dietary deficiency or anemia. Have this checked out by a vet as well.
