My Chico had a small bald spot on one of his upper back leg that I just dismissed becasue it was so small. Last night I noticed that his bald spot has gotten bigger!!!!! I am freaked out! Is this normal? Should I be worried? He doesn't get table scraps, I didn't change his food and he hasn't been scratching there so I don't know what to do now!!! Anyone had this happen to their fur baby? Mine is a about 1 1/2 years old.
