i have different kitty nail clippers, but find that my small human nail clipper works best to trim my furbabies' nails.
Kitties can smell fear, so first of all, you must not be afraid to handle the task. When you are afraid, they are afraid.
With Venus, i sit in a buddha position, and put her on my lap. i lined paper towels at the nail-trimming area. It is quite easy and very fast, i trim it very gently, carefully and briskly.
Be careful NOT to cut it at or too near the quick area (pink inside)... it will create bleeding and lots of pain!!
After trimming her tiny nails, i would normally give a lovely treat, in the form of her favorite baby food, using her special feeding spoon.
It is a pretty fast process for me. Also, i treat the session as a normality, not to make a big deal out of it.. so that she will not nervous or anxious. i prepare the tools i need before hand, when she is NOT watching...
Smiles and Cheers!
