Best Answer: Declawing can be done at any age. Sounds like you are a good and committed owner, so don't be bullied by those ppl that think it is cruel and you are a bad owner. The welfare of you and your future children is just as important as the cat.he can still be declawed, but like many answers you will receive, you should not declaw the cat. It's a surgery that actually removes part of the toebone. If done incorrectly, this can maime the cat and if done correctly, it can be very painful at best.
