My 2 yr old female tabby has had diarrhea and hair loss for the past couple of weeks. She has been abnormally agitated as well. She has always been a healthy cat with very soft hair. I have always fed my cats dry food. I just recently gave her an over the counter dewormer and am waiting to see if that does anything. But I can't explain her hair loss(thinning on the lower back area) or her agitation. I have no money as have been unemployed for several months now so can't afford the vet. Any help would be greatly appreciated.
