When you declaw a cat you are taking away one of their senses. It's like making a cat blind, without taking away their eye sight. They can no longer defend themselves so it can make them a little stressed. You would have to get a softer kind of litter because the kind you may have been using is now uncomfortable on their paws. I do not suggest declawing your cat because then if they sneak out and get attacked by something they have no defense against whatever is attacking them. They can't fight back, they can't climb a tree to get away. It can also be very painful for a cat because they are taking the whole claw out and it's surgery thats not needed on a cat.
A common reasons for people to declaw their cats are that they are scratching the furniture. A work around that it getting more scratch toys for them to scratch and teach them that scratching the furniture is bad. A cat scratches to sharpen their claws just like a hamster chews to sharpen their teeth. So get some of the floor scratchers and some of the pole scratchers or even one that hangs on the wall.
