We use soft paws on our cat & they work wonders. Only thing is they shed off every few weeks and you have to replace them. It took him a while to get used to them, but they don't bother him any more. The reason we didn't want to declaw him is because he has three extra toes on both of his front feet. We thought declawing might cause problems for him because of this.
As far as declawing goes, if it makes you feel any better my mom has two declawed cats. They are both perfectly happy & healthy, no balance problems & no litter box issues (some say declawing causes litter box problems). Both of the cats recovered from the opperation without much fuss and they still leap, climb, play and act like normal cats. I know declawing is not ideal, but animals bounce back from things quickly.
Good luck!
