Declawing is not as horrible as some of those people make it seem. In fact, if you think about it, it is not as big a deal as getting a cat spayed or neutered, and most people seem to advocate that. I'm sure it hurts, but not as badly as having your abdomen sliced open and having organs removed. They may limp for a few days, but they really shouldn't bleed too much. Make sure you use shredded newspaper or special litter instead of the regular kind once the bandages are removed (I'm sure your vet will tell you all about it. And once its paws are healed, the cat will be fine with no lasting side effects if you have a half-way good vet. You already seem to know about not letting the cat outside, which is a good thing. Although I have a friend who has a declawed cat, and she'll let it out in the backyard (which is cat-proofed as good as possible) but only when she is there to watch ans make sure it doesn't get it trouble. It is a big Maine Coon cat, and even though it has no claws on its front (the back claws are rarely removed as they don't really cause damage to anything) it can climb trees by digging in the back claws, and basically standing up-right, kinda "walk" up the tree. Its really kinda funny.
Anyways, I kinda rambled a bit, but I think you get the idea. Its ok to declaw your cat as long as you take care of her afterward, and it causes no lasting damage to the cat.
