For those who have everything: Microchip-activated pet feeder

If you're the owner of multiple cats — and one's a food bully — the SureFeed Microchip Pet Feeder ($150) "will make you purr as loudly as the gadget's whirring motors," says Jonathan Margolis at How To Spend It. The cover won't open until a sensor detects the microchip that's embedded under the correct cat's skin or on a collar-worn tag. The cover closes automatically when the cat moves away, keeping food safe from flies, dogs, and greedier cats. Sure, "it takes a bit of time and patience" to train a cat not to be spooked by the movement, but the "excellent" manual "makes light work of it."
