Hi there,

Being an outdoor cat - this can certainly be due to either allergies or even infectious causes such as bacteria, fleas, or mites.

In a case such as this - I would make sure (if not done already) that your cat is on a safe and effective flea prevention such as prescription Advantage. Even if you do not see 1 flea, there can be 1 on their that causes your cat to have quite and allergic reaction.

Moreover - if an allergic component is possible, I would speak to your veterinarian about the use of either a antihistamine or even a steroid for a short period of time to see if this is effective.

There are specific allergy tests that can be done, most commonly by a board certified dermatologist - and seeing as you have been through a lot at this time - that may be a referral your veterinarian would advise as well.

Please let me know if that helps!
