The Howling Mouse

I wonder if I could get one of these vicious little hunters to keep as a pet?

Before crunching into its prey, the grasshopper mouse howls. The sound is a high, sustained whistle which pierces the desert night. It is as if the rodent is imitating a wolf at miniature scale – the grasshopper mouse even stands on its hind legs and throws its head back during the shrill call. http://www.wired.com/wiredscience/2012/02/mouse-howls-like-a-wolf-bites-like-a-tiger/
