Some time back I saw an article in a cat magazine that had a list of questions to help know when it is time to have a cat put down. The 1st question was "Would you feel an overwhelming sense of relief if you found your pet had passed away peacefully while sleeping in it's bed or favorite spot?" I would very much like to find that again; my Phantom is 19 yrs old and has alot of issues, the vet has tried everything to get the diarrhea under control, diet, meds, but it has gotten no better in 2 yrs. He howls alot, but vet says hearing, thyroid and BP are ok, so we don't know if he is in pain or if he has kitty dementia. It breaks my heart to see him like he is now; I have had him since he was 5 weeks old, but I don't know what is the right thing to do for him.
