I've never declawed my cats. I always just clipped their claws. Some cats are just naturally high strung, but for the most part, they outgrow the wild kitten stage.
I clip my kitty's claws. I don't do it as often as I should, and I didn't start it young enough, so she doesn't really like it. I started my other cats when they were only a couple months old, so they got used to it and learned they'd get a treat for being good. It really cut down on theclawing, chasing legs, and all that lovely stuff.
I've never had cats that were really flat out BAD though, so I can't really offer too much advice. good luck!
