If you have a multi-cat household, hearing a diagnosis that one of your cats has a condition that requires a special diet can be agonizing. How to keep the cats from eating each others’ food? Cats like to eat a little bit throughout the day, and many owners leave a feeder full of dry food out for this purpose.
One way to solve this problem is with special dishes or pet doors that work using the microchip that you probably already have installed in your cat. Cats without a microchip can wear a special tag that comes with the dish or bowl. These inventions make sure that only the designated animal can come through the door or access the dish. So, cat owners can provide the correct special food for one cat without letting the cat access the other food, and vice versa.
