My old moggy has very thick claws. I can deal with those by a combination of careful trimming and peeling. (The reason I do it is otherwise the claws get so thick he can't retract them.) But, he also seems to have overgrown 'cuticles' on the underside of the claws, some completely filling in what would otherwise be a near-normal (for a cat) claw.
I know these are potentially tender, so what do I do?
