I agree with Cataholic...
I have had cats ever since I was little, and never encountered a declawed one or knew of the prodedure until I met my husband.. And my three babies have alll completely recovered and act like any other kitty around with claws. They do not have behavioral problems, or any other problem people have stated here. are NOT skittish, nor aggressive and in fact tend to always find the first stranger in the door and say hello.
I do also, however, think it's awful that people will opt for a declawed cat FIRST before any other cat. That should NEVER be the deciding factor in what cat to get. It should be the cat's personality that leads a family to adopt them.
I am neither for nor against it, and am sort of on the fence. Would it have been up to me would my babies still have claws? Most definetely. Probably because that's part of being a cat. If I get another cat someday will I declaw? Probably not, at least not if its my decision.
If i'm going to adopt a cat will that decide whom I welcome home? NO WAY!
