I'm one who rarely clips. But, since your kitten is very young now is a good time to start. My vet clips the kittens claws when they get their shots. Maybe see if you can get a demonstration, like techiegirl said.
Personally I prefer human nail clippers (good sharp ones!)...but that's just me. With those, I turn them sideways
so I can get a good clean cut in the right spot.
She will probably squirm like crazy the first time you try. Tell yourself that you can do it. If you get it done successfully and quickly, she will learn that it's painless and quick, and that it doesn't pay to squirm.
