my beloved 14 year old siamese cross has a tumour on his back paw, the vet has removed it twice but it has come back with a vengeance. It is really big and has burst through the skin. It is bandaged but obviously uncomfortable for him to walk on. He also has a recently-diagnosed thyroid problem. The vet wants to amputate his leg, but my instinct tells me he won't cope and will be miserable/hate us for doing this to him. He was born to one of our other cats, so we have had him since birth and he sleeps in our bed. I love him so much but don't want him to suffer. My DDs get very upset at the thought of putting him down. The vet wants to operate on Monday, what should I do?????
