Here in Duluth, in a neighborhood called Park Point, several years ago someone released a pair of domestic rabbits, and they bred all over tarnation and probably crossbred with the local cottontails, so now Park Point is infested with hundreds of pet store bunnies and variations thereof. The only link I could find (http://news.minnesota.publicradio.org/features/200005/08_kelleherb_bunnies-m/) sadly does not a have a picture of the black and white mutant bunnies.

(The mutant bunnies are really only in the neighborhood section of Park Point. Past all the rich people houses there is a 4 mile nature trail that is full of all sorts of shorebirds and warblers and beach grass and old growth pines and other things that are much cooler than mutant bunnies.)
