he won't hate you - he'll hate the vet. He'll be glad to see you when you go back to get him. And he'll recover quickly, cats have marvelous recuperative powers. I always have my cats declawed. I know people think that is shocking, but the cats don't give a damn and are perfectly happy. And it makes it easier to live with the cats - no damage to furniture or my skin. Everytime I've had a cat declawed, the cat comes home, gets the bandages off within a day, and is running around quite happily as if nothing was wrong. So don't worry - it will be all right and much better for the cat.
