I am attempting to find a critter to help watch our ~1/3 acre garden come spring. It is fenced in with about 3' high chain link fence and a tight fitting gate. I would like to know of an animal I can put in this pen at night that will help repell deer and other vegetation eating animals from the garden, but can think of nothing that would do the job without eating the garden itself or being vulnerable to nighttime predators. This particular varmint may not exist, but I am open to suggestions, or out of the box ideas.
