If you're tired of listening to the awful squeaking of animal toys, these Soniks squeak toys are your savior. Using the same technology as those silent dog whisteles, the toys will emit an ultrasonic noise that will keep your dog happy without driving you mad. Humans stop hearing things at 25,000 Hz, so the Silent Squeak technology starts at 25,000 Hz and goes to 35,000 Hz. And they're furry and cute too, a small family of aliens from, of course, NoNoyze. They're priced from $4.00 to $9.99 and can be found at most major pet stores.
