A. Your cat is allergic to flea bites. You must do flea prevention (a fipronil spray or spot on or similar flea medication), and you need to get rid of all the fleas in the environment by putting flea powder into your vacuum cleaner bag, vacuuming your entire house (where the cat has access to) including wood floors, furniture, etc, at least 3 times a week and discarding the bag immediately afterwards outside in the bin. You may have to take your cat to the vet to get a steroid injection to initially calm down the skin an allergy.
