To say goodbye to a pet? We have a bedroom cat (rescue and stays in the bedroom as he's never got along with the other 2 cats in the household). He is getting up there in age, 15 years old maybe, and has now been deaf for a few years. Lately he has trouble grooming himself. He is an Angora which is long haired and he's constantly dreadlocked at this point. He also at times now pees and poops on the bed. He's def slowing down. He has a thyroid condition as well. He seems happy enough and always purrs when people are around. He does at times cry a bit not sure if this is pain??? Anyway, when is the right time to say goodbye. I had a cockatoo a few years back who had cancer at 4 years old. We tried surgery etc. but in the end she suffered as we tried to hold on as long as possible. I cannot get through that again, watching such a beloved "family member" suffer needlessly because of our selfishness. Any thoughts?
