Pprovides security against strays. And this cat door does it without requiring batteries or household current!
The secret? The collar key itself is a magnet that actually unlocks the flap allowing access by your pet but not by other pets or strays. Naturally, as with all our pet doors, this one is perfectly suitable for small dogs as well.
A Tunnel Extension is available for installation in a wall and additional Collar Keys for additional pets are also available.

I have used this product for years and still do. I was having difficultly replacing the collar and magnetic keys for my two cats, now well supplied and also added a whole new door for future replacement, although they have been coming and going through the present one for six years. Thanks for your prompt response, as my rescued calico had lost her house key!
