Absolutely 100% against declawing. Personally I feel it would be better for a home to relinquish ownership of their cat to a reputable rescue (not a shelter) rather then have their cat's toes cut off.
To be considered, there are sadly still a ton of people out there have their pet's toes amputated and surrendering/abandoning their pets afterwards. So there are a lot of cats out there that have already been mutilated (sorry there is just no other word for it IMO) that are available for adoption for the people that insist on having declawed cats.
I have two older declawed cats, and 4 fully armed kids too (in addition to any fosters that come and go). With not one piece of ruined furniture after all these years. My oldest declawed girl has an altered gait and is a biter, a common side effect to declawing, and the other one has a persistant limp. And any time she sits, and always holds one front paw up. I'm ashamed of myself still after 11 years for allowing them to be mutilated b/c I followed the train of thought that it was "just what you did to have a cat"...

I'm fortunate that they do not have litter box issues as so many other declawed cats have gotten.
