My cat scratches and chews her hair out. Is it allergies? What helps?

Pet's info: Cat | American Shorthair | Female | spayed | 1 year and 5 months old | 7 lbs

Annabelle has scratched and chewed her hair out since we adopted her 6 months ago. My vet gave her a depo-medrol shot which stopped all that for a couple weeks but now she is back at it again. Could it be allergies and would Benadryl help? If so how much? She weighs 7.8 lbs.

There are no medicine safe for cats over the counter. If the steroid injection helped, then there is a good change it is from an allergy. You will have to talk to your vet about a long term solution such as a diet change or allergy testing to control the signs since long term steroid use can have unwanted side effects such as weight gain and diabetes.
