Completely against. I think under no circumstance should a cat be declawed. There are so many alternatives, and if you're proactive with your behaviour modification, then you should be able to curb the inappropriate scratching. I recently had a huge issue with my brother and his GF (mostly just his GF) over the possibility of them declawing their cats. I won-yay! And my brother has informed me that he is now trimming their nails regularly without any problems. Educate those around you, I think most people don't realize that it is in fact an amputation, and alot of vets don't volunteer that kind of info when asking if you'd like to have your cat declawed.
