Practice coming and going. If your cat starts to get tense whenever he hears you pick up your keys or if he sees you reach for your purse or coat, then practice doing those things several times a day without actually leaving. Pick up your keys and put them back down. Do this multiple times. Later in the day, walk to the door and then back. Do that several times. Now, put the two together – pick up your keys, walk to the door and then back. Later in the day, put on your coat and then take it off and then add all three together – putting on your coat, getting your keys and walking to the door. Work up to actually walking out the door and then immediately returning. Each time you walk back into the room, greet your cat casually or engage in a little play session. Vary the times you do these training sessions throughout the day or evening. Gradually increase the time spent outside of the home.
If there are particular objects that trigger the anxiety such as your keys, your purse, your brief case – then carry those around the house for a while each day so they are no longer an anxiety trigger.
TV and Music
There are cat entertainment DVDs on the market showcasing prey and other little interesting critters. You can have one playing when you’re set to walk out the door. Put the TV on a timer so it’ll go off after the DVD ends. For music, set the radio to a classical or soft music station. Just having the music in the background may help serve as a buffer for any outside noises that might trigger kitty’s anxiety.
