ok so i have a 14 year old cat that just recently that a patch of hair on his stomach. he seems fine with no other symptoms except he seems more vocal lately, not an 'in pain' meow though. i have two thoughts on it, it may be old age (?) or he is stressed. my dog just died a week and a half ago, and they were very good friends. my cat has been sleeping in her (my dogs) bed and other places my dog used to sleep. i need to know whats going on, my cat is my life. any thoughts????
