You might want to try covering her face too.. sometimes if they can't see they give up the fight. I've known people to put their cat in a pillow case as well, with only the paw to be trimmed sticking out It creates some funny pictures in my mind but it might be a traumatic experience for your kitty. Does she claw on the furniture? If she goes outside at all it's best to leave her nails long anyway. Anyway, I hope you can figure something out!!
