Hi Tim,

Being an indoor cat - although less likely, infectious causes such as bacteria and mites should be ruled-out. It would be a shame to run many tests or make significant changes if there was a bacterial infection that required an antibiotic.

If there is no infectious cause, just like in people and dogs, cats can have allergies - either environmental (pollen, mold, dust, mites) as well as to food.

If this is the case, and we rule-out infectious causes, you may elect to discuss a food trial with your veterinarian or even a trial course of an antihistamine or steroid to decrease the behaviors and skin issue you are reporting.
