I have been cutting my cats' claws ever since I got them. It's a good thing to do if you're having trouble with your cat tearing up the furniture or the carpet. It's especially good if your cat is inside-only, as being outside they can more naturally keep their claws trimmed.
It's really not difficult to trim the claws; the hardest part is getting your kitty to cooperate. We like to do it in the evenings when our cats are more sedentary. We usually wait until one crawls in our lap to fall asleep, and then we gently pull out the clippers.
You can use regular nail clippers, but we have nice ones made for cats. I've used both and I think the latter is worth the $5. :-) You can buy them anywhere that sells pet supplies - we got ours from Wal-Mart.
When you're about to cut your kitty's nails, you'll want to get a firm hold on him. Gently press on the pads of his paw to make him extend his claws. Then gently clip each nail while continuing to keep the claws extended. Be careful not to trim too far down. There is a soft pinkish area called the quick that has the nerves and blood vessels that are found in the cat's claws. Trim just before the quick, and if in down just trim a little bit. Take it easy - if you're relaxed, your cat will more likely be relaxed too.
This is just a basic overview. I may int he future address what can be done if your cat isn't as keen on the whole nail-clipping idea as you are. :-)
