I know how to trim cat claws, but after trimming do I smooth it out with a nail filer?
I clip all my cats' nails. I use a human nail clipper and do not need to do any filing.
Get your kitten used to nail clipping very gently and gradually,with lots of soft talk, pets and even treats. Try and do it when the kitten is sleepy and never force it. If the kitten struggles, gets frightened or resists, stop and try again the next day. Introducing this now will make things so much easier down the road.
