I have a question that some of you might fine disturbing but it is something that is going on with a friend of mines cat. My friend has a female cat about 16 yrs old, and she is plagued with health problems. She has just recently stopped eating and she smells terrible, I know that she has had problems with her teeth in the past and she also does not groom herself so she has to be shaved, I feel so bad for snowball. I have tried to gently suggest the possibility that she may need to be put down. Do i just sit back and watch this animal get worse or do i talk to my friend again about this subject?
