I've assisted in many many declawing surgeries and the more I see it the more I wish people knew what exsactly happens to their cat when they drop him off to be declawed.
I would rather see a cat be declawed rather than be dumped off at a shelter(where he could be euthanized) because he was clawing the furniture but at the same time most people do not look into the alternatives. I think if they took the time to train the cat to using a few different scratching pads most declaws would be avoided. There's also a product called soft paws that is sold at pet shops and it's basically plasic caps that are glued onto the cat's nails. I've never used it on my cats but a few people I know like them.
I have 4 indoor only cats and I regularly trim their nails and have a couple scratch pads around for them. Yes I will catch one of them occationally scratching the sofa but it's not often.
The cats who go through this surgery are in ALOT of pain once they wake up from anesthesia and often times are aggressive(when they wake up). Generally no pain medication is given after the fact but just recently the clinic I work at will give an injection of Torb the day after. There is no other way to describe how their paws look after this surgery other than RAW.
There's also a link a couple of the members have posted that shows pictures of a cat being declawed. I don't have the link but I'm sure it will pop up.
If you decide to adopt a kitten and you run into scratching problems please excercise all the other options because it's not a "simple" procedure. If possible have you considered adopting an adult cat from a shelter who has already been declawed? You would be giving a cat a good home and not subjecting another to being declawed.
