Bowl and collar technology

If you have more than one cat in your home, you may be aware of the problems of feeding them: one cat may hog the food, one may insist on eating before the others, they may (because of age differences or other factors) require different types of food and so on.

In past times, owners worked out their own ways of dealing with these problems, but, of course, the pet product manufacturers have come up with their own clever high-tech solutions. One is a food bowl that links up electronically with a special collar worn by the cats you don’t want eating from that bowl. If a cat wearing the collar nears the bowl, the bowl emits a tone that makes the cat skedaddle. (Are human beings clever, or what?)
