My cat is 1.5 years old, here recently the past couple of months, she bites, scrathches and pulls her hair out. I cannot afford to take her to the vet but I like to know if someone out there can tell me what I can do to relieve her discomfort, I do not like seeing her biting and pulling her hair out and she has bald spots/paches all over her back area on the tail and back legs. I need someone to please tell me if its fleas or some kind of allergy my cat has?
