I find declawing is cruel. I've had 4 cats in my life. Two of them did destroy furniture, the other two never did. The one I currently have hasn't destroyed anything and I've had her for nearly a decade. Personally I wouldn't be able to bring myself to declaw her or any other cat I own.
IMO, when you buy a cat you're choosing the cat over your fancy furniture, either that or you at least do so knowing you'll make an effort to get her to scratch elsewhere. If you're the type of person who chooses fancy furniture over your cat having claws you probably shouldn't even own one. Like those people who leave their cat when they move because they chose to move somewhere that doesn't allow them or don't want it ruining their brand new house
I understand you don't want your material possessions ruined and some cats are little ***** when it comes to that, but personally I don't think you should even have a cat then if you're more concerned with that versus allowing your cat to have claws.
