My cats been acting strange lately, she's eating the dogs food and now she's licking herself and scratching so much she's losing hair. Is she just stressed out or is it fleas oris it related to eating the dog food, I have no idea but it makes me nervous because she's losing hair very quickly and it's to the point where she's getting raw spots. When I shoo her from licking she gives me a nasty look and continues to chew, she's like a chewing zombie. One thing I want to add is that my sisters cat has had the same problem for years, I moved in last year and my csat is just now having the same problem, however my other two cats aren't having the problem, I'm so confused.
