Who's afraid of the big bad cat? Not this mouse, that's for sure.

With the help of Japanese scientist this mouse got her genes "improved" so that she can't smell cats. Her instinct tells her to play dead if she smells a cat, but now she just plays with the cat like any other hairball.

Implications - Domesticated house pets are a fixture in nearly every home; unfortunately, these animals still have an innate prey drive. Researchers are exploring ways to thwart this prey drive through science to create "hacked" animals that look and behave just as their owners prefer. Hypoallergenic dog breeds and cats that don't chase mice are some of the many manifestations of this theme.
