I'm so sorry about Sooty.I too went thru the same with my 16 year old KiKi a couple months back.He had cancer in the jaw and the vet said half the jaw would have to be removed but they also said even if it was a young cat that noone should put their pet thru this removal.It's painful even after the cancer removal and not comfortable at all.And brings their spirits down forever.I'm glad you made the right choice.
I really am so sorry for what you are going thru.
But I'm so happy you joined pettalk.We will all be here for you.
