However, in authentic mutilation cases

The predators will NOT touch such a carcass . . . usually for YEARS, IF EVER.

I am not convinced there are "authentic mutilation" cases.
In some cases the small varmints entered into the carcass through the anus and ate the animal from the inside. It appeared from the outside that nothing had disturbed the dead animal except those tender parts and the eyes. But if you want to believe in alien cow abductions go right ahead.
