Are you prepared to take on this cat's needs for the next 14-18 years? If the surgery is unsuccessful (the most likely outcome), how will you feel about making a decision when this cat is no longer in medical distress but requires assistance for mobility & peeing/pooping, when you've begun to form an attachment? Will there be muscle atrophy? If so, what daily therapy will you have to do with this cat?
Whatever you decide, I'm glad you took this cat to your vet. At least he is being cared for and his pain is being managed.
