I fyou do decide to get a cat declawed, I think that it would be best to do it when they are kittens, and when they aren't as used to them. To get an adult cat declawed is not a good idea because they have lived with them all their lives, it would almost be like getting your fingers cut off when you are 25 years old. If you are worried about your cat scratching furniture, try getting a clawing post, and if they scratch anything but that spray them with water, most cats hate that and it doesn't hurt them and they will learn. Another thing you can try is trimming their claws with clippers.
