Yup have seen those on TV & in magazines && dont believe in them.. I do not under no condition ever alter my babies abilities with any of their body parts ( no declawing - no toenail pads - & ect.) the only thing I do beleive in is Spaying & Neutering.. If you are going to have pets {cat or dog} in doors then deal with furniture & or what ever in a manner that does not hurt or discomfort your babies.. WOW I will get off my soap box now ..
