You tell 'em Katie!! I have a combination also. My oldest cat, Mollie Rose, 16, is declawed and she is the most loveable, sweet cat I've ever had (aside from MooShoo that is).

I'd say give this poor kitty a test drive. Ask the vet to take her home and love the heck out of her. Gradually introduce your cats to her (or him) like you're supposed to. You might be pleasantly surprized. The reason why she's hissing at people is becasue of what your jerk of a vet did. He should be ashamed of himself. It was not his decision to make. It should've been the new owner's that decide. Then if they did have her declawed, shame on them.

MrsCat,

Declawing is not just plucking out the claw, it's chopping off the the nail at the first digit. That vet should burn in hell for what he did.
