Thanks you guys for all the good thoughts. Yeah, Norm was quite dysfunctional when we brought him into the house. Here we had all these goofy, fun-loving, hard playing guys and Norm just wanted to hide in his cage. It seems like he responded to the younger ones first (playing and wrestling) and now he's figuring things out with the older two. I think he really hated our neighbor (good taste on his part, I say).
I think he has potential to be a snuggle-up-on-the-couch cat. When that happens we'll have a BIG PARTY.
