Walked around like he owned the place, never bothered any of the other cats and has bonded very tightly with Charcoal, the other male cat.
Somebody rings the door bell, Jack is the first one by the door, no matter where in the house he is. Somebody sits down to eat, Jack sits nicely at the table beside that person, always hoping for a handout.
Somebody is brushing their teeth, Jack is on the vanity watching you closely, almost saying 'let me try this too'.
Somebody is having a shower or a bath, Jack is sitting on the edge of the tub, my daughter calls him the creeping peeper.
Somebody is making lunch or breakfast, Jack is always at your heels, hoping you might drop something and he can pick it up.
Whereever I go in the house Jack is sure to follow. I have the bad habit of walking through the house while brushing my teeth, so that totally confuses him, but he is right beside me wherever I go.
Time on the computer can be quite trying, because no matter how many times you put him back on the floor, he just doesn't get it. I guess catching cursors is quite interesting.
He loves to play with the camera too and is always ready to pose for a picture, or at least be in it.
Besides being always at your heel, Jack has some weird habits too....e.g. he has a thing for drinking straws, so whenever somebody is having a drink with a straw he sits beside you or in front of you staring you down in the hope that when you are done you will give him your straw to play with, there is quite a selection under the couch, and if you don't watch out he steals the straw right out of your drink. He loves eating peanuts and is constantly cracking shells all over the house and eating the nuts, he needs to learn how to pick up his mess and throw it out.
