Itching in cats is caused by one of the following: parasites (such as fleas), allergies (such as to food or pollens in the environment) or behavior (usually stress related or boredom). Lab test for food allergy can give unreliable results, so try giving your cat a hypoallergenic diet. If this makes no difference after 8-12 weeks, then you need to review her lifestyle to see if she is stressed, bored, or being bullied, as correcting this will help resolve the itching. Topical treatments are unlikely to help.
