This may be the case with some cattle mutilations but this explanation cannot account for human mutilations. Also it is said that these cattle mutilations are done in a very short period of time. One report of a farmer and his wife states that while they were tagging cattle one was mutilated. They finished tagging it and moved over the hill to the remaining cattle when they were finished and returned up the hill the cow was mutilated. They say this was done in no more then a fifteen minute window and as mentioned above there was no blood on the ground or on the animals hide. They brought in a professional tracker and found no footprints around the animal (except for theirs of course). If this was rural kids as you suggest they deserve an award.
