What's wrong with my cat?
She is 2 1/2 years old. I have had her from birth, her mother was a stray. She is white, small, and very skinny. She always scratches her neck area, and it leaves scabs. And she chews her stomach, tail base, and anything in her reach, which leaves patches. She has excessively groomed like this for about a 1 1/2 years but it's getting much worse. The house is pretty clean, and I have 7 other indoor/outdoor cats who show no problems. Is it a skin condition or an allergy perhaps?
