No insect or animal chews on an animal carcass with surgical, laser-like precision. They also don't drain the carcasses of all blood, leave no prints or evidence, or drive off normal predators like coyotes and wolves.
Yet ranchers and competent professionals have been reporting those exact descriptions of these mutilations for at least a couple of decades now, and from all across the country.
If insects are doing this, then why hasn't a single rancher or eyewitness reported seeing them on one of these mutilated carcasses before? No one's ever seemed to have caught them in the act.
If insects are responsible, why don't they attack whole herds?
Why just one or two select animals at a time?
Why just cows, and not other farm animals?
Why aren't deer, elk, moose, and similar large hoofed animals ever found in this condition?
Logic dictates that it's not insects or animals doing this. The physical evidence begs some other explanation.
We have an elderly retired rodeo bull named Sauce who will die of natural causes very soon. When he gets down and can't get up I'll freepmail you and you can come down here and set up camp so you can see it all with your own eyes. Deal? :)
