In my house, there is a door in the kitchen that goes to the basement stairs. We put a cat door in it, and a fancy one at that. It has switches so that you can control which directions the cats can move. We needed this because our 3-year-old cat Janet wants to play, and 8-year-old Phoebe does not, so Janet ends up in time out to give Phoebe a break. It took Janet MONTHS to figure out the door as a concept. This week she figured out the switches and time-out is no more.
