TITLE: Declawing advice!
POST: I have a 1 yr old polydactyl cat that has 9 toes on one front paw, 8 on the other and 10 on each back foot. We've had her about 9 months. 

Her little monster paws have issues with ingrown claws. We clip her twice a week but they still turn in and the vet said it would be best for her to get rid of the ones that are constantly growing back in. Also, she has minor walking issues probably due to the pain of the claws.

Which leads me to our dilemma...she's going under for 3 claws to be removed, should we remove the rest? She is a terror and rips up everything but could that be the pain from the claws? 

Also we have BARELY gotten her to start using the litter box as she is a very difficult cat. If we get her declawed, does that mean that she'll start having litter box issues again?
TL;DR: 
poly cat has medical need for 3 claws to be removed, should we do rest while she's under and what are consequences typically behaviorally?
