Well, at least now you can feel you’re really a part of the PT family! LOL.
Seriously though, could you just put the sentimental furniture away? Declawing really is a painful and yucky thing to do. I had a kitty that I adopted already delcawed. I doubt your kitty will harm your chi on purpose. If you think that the kitty really will harm Tiny, I’d seek out some professional advice from a behaviorist.
