My cat constantly grooms herself, sometimes licking the hair off her back and inside her legs. I don't see any fleas. What else could be causing this?
Cats are meticulous groomers that spend a great deal of their time cleaning -- after meals, and before and after naps. If, however, you are noticing hair loss, this can be a sign of a problem that may require medical attention.
There are many reasons for hair loss, including, but not limited to, compulsive behavior, external parasites, stress, bacterial infections and allergies. Don't be quick to rule out flea-related problems, though. Sometimes cats are such careful cleaners that they rid themselves of all outward signs of insect infestation.
Hair pulling and chewing are warning signs that your cat is uncomfortable. Your veterinarian can help you get to the root of the problem and start appropriate treatment. Try to schedule a full checkup for your cat as soon as possible.
