Looking for helpful hints to help deal with cats claws

See if someone had left me this kind of advice on my post, then I would have had a better opinion of why not to declaw the cat. I do see everybody's point with the declawing issue, but nobody was giving me any advice on how to prevent the scratches besides don't get a cat. I think that if you are going to criticize, then you might want to give a better suggestion. I like this cat nail cover idea. How long do they stay on? How often do you have to change them?
