Have you tried the double team approach? Someone holds kitty while the other person clips kitty's claws? This is the method I use, though my cats are used to it since I have been doing it since they were little. My friend uses the same method and has success with it, and her cat is a bit more annoyed by the claw clipping.
I sit "indian style" and hold the cat in my lap her back to my front. One hand under her front paws, the other above her back paws on her tummy. I am able to hold them like that and hold out their paws one at a time for my friend who does the clipping for me. I think (and this is just my opinion) you have to be consistant about it. I do it once every two to three weeks, and as time goes by they get more mellow about the whole process. We do have set back where one wants to be difficult, I basically don't allow it. I know every cat owner is going to laugh at me and if my cats could read I am sure that they would disagree, but ultimatly I am the human and they are the cats, and this is what needs to be done for them and me to remain healthy and happy
. Go on. Laugh. It's ok.
Don't get me wrong, the little furrbals trounce all over me most of the time, but in this I don't bend. Nails must be clipped. End of story
