I have a 9year old female maine coon named molly[emoji]128571[/emoji] she is an indoor cat few months ago she got fleas i treated her and they seem to have gone, but things in the house hold have changed and her behavior is different she has been chewing on her side so bad you can see red bleeding skin, it would get better and she would do it again my ex fiance was living her since shes been with us 4 years, he is no longer here due to domestic violence issue wondering if its possible that molly is depressed people have said they get that way when theres a change, molly was with him all day while i worked, but ihe has been gone 2 months now, she also seems to be hungry all the time. Any advice would be greatly appreciated, thank you
