Take back your yard like Dirty Harry

Let's say you have a backyard rodent issue. A big one. So big that you can't watch Caddyshack anymore without getting a tic.

The "Mega-Sonic Scatter-Cat" device supposedly "repels dog, cats, squirrels and other nuisance animals without harming them," according to Pocket-lint, using sonic and ultrasonic waves instead of buckshot. But who are we kidding here? Rather than something like the passively situated "Solar Chaser," the real reason to get one of these is to pretend you're aiming Harry Callahan's .44-magnum at the dastardly four-legged vermin up to 65 feet away.

In a perfect world, perhaps this technology will be developed for bi-pedal pests as well.
