Missing the litter box
A cat that’s stopped using its litter box might be sending a message by marking its territory, but you’ll still want to take it to the vet. What you assume is a behavior problem might actually be a medical issue, such as bladder cancer or a kidney stone, says Dr. Rossman. “It’s always good to rule out the medical things first because those are easier to fix than the behavioral ones,” she says.
“Most neurologic things a human would have, a pet can have as well,” says Dr. Rossman. Especially if your cat isn’t an epileptic, you should be concerned if you see it roll back its eyes, lose consciousness, or lose control of its bowels. Put it in a padded area without getting your hands near its mouth, then call the vet ASAP, she says. Avoid these other 12 dangerous mistakes cat owners should never make.
If your cat is suddenly and excessively drooling, that could be a sign of any number of health problems. Some issues that cause cat drool are dental disease, kidney failure, and cancer, among other others, according to Pet Health Network.
