J- it actually depends on the cat and the personality plus the age. For a kitty to be declawed, the whole knuckle is amputated not just the claw itself. It is a very traumatic and painful thing for a kitten or cat to endure. Like people, some cats can tolerate this type of pain and some can't.
Declawing should be outlawed in the United States and many cat lovers are working to make that happen. It is a money-maker for vets and a lazy way that some owners use to discipline their cats. There are so many better humane ways of teaching cats to not claw furniture etc. I have 12 cats all ferals and they are inside outside kitties, and the only furniture they claw are their scratching posts and an old couch upstairs. You have to invest some time and effort and have patience, but you can teach a cat not to scratch on fine furniture.
I also hope you are not using clumping litter in your cat's boxes, because that could lead to problems down the road, the litter can work its way into the soft part left from the operation and cause the kitten a lot of discomfort.
If you are strong enough, you might want to take a look at the link provided, and you will be able to see what your kitties have been made to endure. It is not pretty, and if you do not have a strong constitution, I do not recommend you go there. I just hope and pray that in the future, should you add another cat to your family, you will think long and hard before you decide to have it declawed and do the best thing and decide not to have any more of your cats or kittens declawed.
If you think I am being rough with you, I am not. This is just a sensitive subject for many involved in rescue. Many declawed kitties and cats develop behavior problems after declawing. I am working with one cat owner now trying to help her declawed cat. He is now confined to a cage for what looks like the rest of his life because of his issues following this procedure.
Just educate yourself before you decide to have a cat's claws amputated and know that cats are very adept at holding in pain. You may not know it, but boy do they hurt. They learn to mask that pain in the wild, that is how they survive.Declawing
