In my multi-cat household, food stealing is a big problem. To add to the issue, one cat needs to be on a low-calorie diet yet frequently insists she's "starving". The SureFlap Microchip Pet Feeder is the perfect technological solution. The feeder recognizes my different cats through their microchip (which is a good idea to have anyway) or you can use the SureFlap RFID collar tag. When the right cat approaches, the lid over the feeding bowl opens and remains open until the cat leaves. Genius!
