Does your cat lick until her fur falls out? If this is so, she may suffer from an inhalant allergy. Did you know that feline skin allergies are very common?  Food is not the only cause. Sometimes cats are allergic to pollen, mold, mildew or other things in the air. The same things that trigger hay fever in humans can make cats itch like mad.  Sometimes the itchiness can be so uncomfortable for a cat that they will lick themselves until their skin is raw.  This problem can be seasonal or year round.  If your cat has these symptoms, take her to your vet for an accurate diagnosis. An allergy test can help determine the cause.  Pet medication such as an antihistamine, allergy shot or steroid treatment is all that is needed to help solve the problem.
