Kottentail (2007)

The "Overlook Animal Research Laboratory" has long been working on genetic engineering without any trouble. That all changes one night when two would be animal liberators set free a test rabbit, not knowing that the bunny's genes have gone haywire. On the loose, the vicious little beast soon attacks a farmer - Hans Kottentail. Hans quickly begins to change. He grows fur, eats veggies and... hops. It isn't long before murderous a rage overtakes poor Hans and he begins picking off townsfolks at a rapid pace. It's up to 5 local women, each with ties to the case, to bring him down before he kills them all.
