A couple of years ago some of the neighbor kid's 4-H projects seem to have escaped and started inter-breeding with our native cottontail rabbits. We now have wild bunnies in several shades of blonde, along with a solid black one every so often.
The new bunnies are also quite a bit larger than the original cottontails. Several of them have become quite tame and will eat out of your hand. We've named a few of them, and they will sometimes come when you call them!
They are kinda fun to have around, that is, as long as they stay out of KeeWee's garden!
