Are cats supposed to go outside again? If so, the SureFlap smart pet door might come in handy - everytime a feline heads over to your door, SureFlap tries to read its microchip ID. If it's your cat, the door opens up; if not, you'll probably be up all night listening to a strange cat howling on your front porch.
SmartPlanet says this device costs about $150, but it can recognize up to 32 different cats So if you feel like throwing an exclusive cat party with Keyboard Cat, Maru, Doctor Cat MD and other feline big-shots, well, party on, man.
Now it's your turn - share an awesome link or two in the comments. Our ID system will know it's you, so you won't get blocked.
