Changing cat from indoor/outdoor to indoor only

Another way to teach the cat not to rush the door is to give treats in a spot near where you enter and exit. Each time at first and then after the behavior is established, taper off if desired. Something high value. This works amazingly well, unless you have a really dedicated escape artist. Creating the expectation of a tasty treat when you walk in will do a lot to counter the temptation of an open door.
