The very latest in Infrared cat door technology ensures safe access for your cat. One of the most reliable automatic cat doors on the market! Prevents strays from entering!
Your cat wears a collar key that transmits a digital coded infra red signal to the door which unlocks the door. The range for the collar key is approximately 6 inches.* One key and collar are supplied for use with one cat. Additional collar keys can be purchased for use with two or more cats (sold below).
The door is battery powered and programmable (requires 4 AA batteries). Batteries should be replaced every six months. It can be upgraded to run on AC power by purchasing a Transformer Assembly Kit (sold below). This electronic door opens using a "programmed coded" collar key. The key(s) is specific to your cat or cats and the door. This means that other cats in the neighborhood with collar keys (magnetic or coded) will not be able to open the door. In contrast, a magnetic door uses a simple "magnet key". This means that any cat or dog with a magnet collar key can open a "magnetic" door.
Note: This door only allows cats with a programmed collar key to enter through the door. A collar key is not required to exit though the door to the outside.

Choosing the correct size door for your pet is not difficult.
Remember you can always get a door which is a little bit larger, but do not get
a door which is too small. Here are some guide lines and suggestions to help.
If you have more than one pet, you will need to focus on the larger dog.
