Hi, Ben, and welcome! Kittens are much more hyper and prone to destroy things (my kitten just broke our lamp last week), so an adult cat may be the best thing for you! The only problem is if an adult cat has been raised outside, they are sometimes not happy being inside. So you may want to see if you can get a cat you know a little history about. Sometimes people will post notices at vets, pounds, stores, etc. about inside cats they're looking for a home for for one reason or another. That may give you an idea of the cat's personality more if you're really concerned about getting one certain type of cuddly-bear personality. Or you could really spend some time at the shelter and try to get to know a few cats, get them out and interact with them. You can probably spot the cuddle-bears pretty quick!
Or you can be like me, and get 4, so you have every type of personality possible!
I have a mean kitty, a cuddly girl who is a spook to everyone but me, a funny guy who likes to show off, and a rip-roarin', attention-hogging, constantly yowling kitten.
Getting 2 may be good, but maybe not. My 2 littermates fight constantly, so it's not always a guarantee that they'll get along. I probably wouldn't get 2 adults at one time, certainly...
Good luck and let us know what you end up with!
