Yes, declawing a cat is a very outdated measure that was only invented for the benefit of human upholstry. sp? When a cat "sharpens his claws" he is not showing aggression or trying to ruin your couch, he is trying to rid his nail beds of dead skin. If a cat has been treated well as a kitten, then spayed or neutered, there is no reason his claws should be a threat. I worked at several veterinarians, and the way some of them do this "procedure " is quick and horrible. And it's true, taking the nails from all 4 paws is a death sentence for a cat that gets out, they can't escape by climbing a tree. Nowdays, with all the cat viruses, a cat should be a totally indoors, vaccinated, spayed or neutered friends with evey claw in tact. Do provide him with a scratching post. One made of sissal or sissel? sp again works best. It feels good to cats nails and does not mimic any rugs or furniture.
