Does anyone know how much it cost to get my cat declawed?

No clue. Call them.

Don't. Do it. Get a cat post scracher. It hurts the cat and considered mean.

I would call them and ask. When we were first considering a pet 10+ years ago they were very good about answering my cost questions with regards to immunizations, yearly exam costs, and neutering.

I am not sure if CSAC will even do it. How old is the cat.
