I don't understand why if your rental agreement states that your cat must be declawed that people feel THEY are the one that needs to declaw it. Shelters already have cats that are declawed and in need of homes. My sister wanted a cat and she had a rental agreement that stated only declawed cats, she said she couldn't bring herself to adopt a kitten and get it declawed so she adopted one that already declawed. Yes maybe she didn't get the cute 6 week old kitten, but who cares the kitten will grow up! She also had a roommate with an older cat and the two got along fine. I've seen lots of older cats be introduced together and it be sucessful.
