I clip Fister's nails about every week/10 days, but I could not have done it when he was younger. Couldn't even get hold of him and lift him. Now, I do it by leaning over him from behind, have treats ready beside and start by giving him kisses on top of his head and massaging his paws - he likes that. If you put your knees close to his body, then he won't be able to run off.

I bought the scissors at the vet, he said it's the same he uses, and they are cheap.

Good luck!
