I have two cats that like to come into the model room. One will just come in and curl up at my feet or on the chair next to me and be perfectly content. The other will cry at the door and scratch at it like Marks cat but when I let him in he wants to get into everything until I get mad at him and kick him out. Then we start the whole process all over again, scratch, let him in, get into everything, kick him out. Repeat again and again.
