@Janeway, I think you would do better by trying to get her used to handling her toes and work your way up to trimming her nails. Don't make a big deal out of it, just go slowly start by touching her paws, then her individual toes then separating her toes apart and handling them and finally get her to where you can manipulate her feet and press her claws out. Give her treats each time she lets you touch her feet and teach her that footsie time is fun time.
I have a small pair of cat nail clippers that I use and it's always done in just a few moments, he gets his treats and we're all happy. It took a little while to get him used to me handling his feet but now he's just fine. He knows it means extra treats, praise and cuddles from me.
