K-K,My Rocky,who is an older version(14yrs)of Sparky would never accept a new cat in to our household.
He's fine with my other 2,but he knew them since kitten-hood.
Chico and Rocky will sometimes have a spat,quickly broken up by us throwing a pillow at them,or something like it...never ever break up a fight with your hands,but I am sure you know that already.
