Get him fixed and he wont likely spray unless something bothers him about his home...like a new baby or something like that. Not that new additions (human or animal) make them spray, that's just the most common reason for sudden spraying.

Boy cats are really cuddly and laid back...at least that's how it is with my eight. (4 males 4 females) The boys are really mommy's boys.

Congrats on the new kitties! Do they have names yet?
