I didn't have this issue with my 4 cat when i do that, i usually have them belly up on my lap, head facing me, and i trim it that way so their paw won't be in an awkward possition. They will try to get away, but i'll just grab them back and give em some head scritches to quiet them down. I sometime will grab their paw when giving them pat and ask "lets check your nail. can i trim this?" and then trim it. Usually they let me trim one or two before getting annoyed.

I did it like this on my sister's cat as well, works just fine.
