Getting a 2nd cat - good idea?

I think an extra cat is great if they get along. Cats are fun. Be careful though, you don't have a cat, you have a kitten. Most kittens become significantly less playful as they age. You may be disappointed when you end up with a family of lazy furballs that just lay around all day.

This is an awesome point - my big concern is having to rid myself of one or both of these if life circumstances dictate as such in the future. Let's face it, cats are a 10+ year commitment, particularly indoor ones. Anyway, I do realize they outgrow the kitten stage and become very sedentary, but research with some cat-loving IRL friends indicates that you can bring out the kitten in the older ones with the right toys, and that some of them become very affectionate/loyal as they age (which of course is a trait more commonly associated with dogs).
