It’s a pain to let your cat in and out of the house, especially at odd hours in the early morning.  But if you install a cat door, who knows what other riff raff may be creeping through that door?  You may wake up with a living room full of possums.

Enter SureFlap.  The company’s Microchip Cat Flap uses wireless technology to recognize the ID chip already implanted in your cat to give your pet access to your home while keeping out “marauding intruders.”  The door works with 15, 10 and 9 digit microchips, and can store up to 32 different codes if you’re one of those…you know…cat people who have 32 cats in their home.

Sure, you do have to train your cat to actually use the Cat Flap, but once that’s taken care of your cat will be able to enter and leave when it chooses, while unauthenticated animals will be locked out.  You can also manually lock the cat flap to prevent your cat from leaving the house altogether.

The Microchip Cat Flap is a pretty ingenious use of a cat’s ID chip.  I’m not sure how many cat owners with pet doors actually have random animals entering their house, but this seems like a pretty valuable solution for those of you that have this problem.
