answer:I’ve never sanded them, but I have clipped cats’ claws. One was very mellow and didn’t care, the other two freak out from the moment I hold a paw. Lots of twisting and fighting. However, I have learned that if I catch one of them while he’s laying in the sun or in front of a fire, he’s too mellow to care. I have heard that if you start them early and get them used to touching their paws, they accept the clipping more easily.
