Perfect Pet Electonic E-Cat Door, Medium in White. Perfect Pet. https://www.petco.com
Our E-Cat Electronic Pet Door allows you to limit access to your pet only, preventing wild animals or another pet from getting into your home. This battery operated pet door does not require plugging into an outlet and includes a color with breakaway clasp. Attached to the collar is the E-sensor key pendant which activates the door's electronics
The strong telescoping ABS plastic frame adjusts to fit most door thicknesses from 1 and 1/4 to 1 and 3/4 inches. And the flap size is a generous 7 by 9 inches, and is made of unbreakable polycarbonate. A three-way lock allows you to select from the following positions-- open, allowing free access in both directions, active, allowing only your pet entry, and locked both directions. In the active position, as the pet approaches the door from outside, a switch opens the lock and allows your pet entry. In a few seconds, the door relocks itself. Extra collar and key sets are available for multiple pet households.
