Not sure where Tom fits. Inside the house, he needs to know exactly where I am at all times, and will call for me if I disappear to another room whilst he's napping... He will check on me from time to time, but won't necessarily have to be in the same room, though he does like to be able to see or hear me from wherever he is. He goes outside without me (but I'm indoors so I must be safe, right?) but doesn't stay out long anymore. If *I* go out, though, he has to be with me. He tears at the front door to go out if I am out front, or, if out back, he follows me around the yard. If I stand still for long enough (waiting to photograph a bird or bug) he will sit or lay at my feet until I move again. Thats why so many of my Tom-outside shots are of him in the grass...
At night, all bets are off. I am to remain in the house, and he goes and checks the territory to make sure we have not been invaded. A second check must be done before dawn.
