In my 50 years in the veterinary profession, I have declawed many cats. I would not think of declawing a cat without first giving it anesthesia. I couldn't believe when I read the state of New Jersey is thinking of banning declawing cats. The bill has passed in the House, but is still waiting for Senate approval.
One-third of a centimeter of pentobarbital given subcutaneous is all it takes to put a cat to sleep so that you can declaw the cat painlessly. I could not think of doing it without putting the cat to sleep because the cat would fight and bite me, and I would not blame it.
