Just don't clip up to the pink part and youre fine. I use regular fingernail clippers for that.

My wife showed me some advice online to hold the scruff of their neck in your mouth like a mama cat would while clipping. I tried it and I was able to clip all the claws on my 23 pound cat by myself. He barely freaked out and he's a huge baby scaredy cat about everything.

I did get a mouthful of hair but it was worth it.
