The wild scavenger animals here were supposedly "short-tailed weasels" aka ermine, which are small, nocturnal, elusive animals that live in wild brushy areas. They do not hang out in town garbage dumps to scavenge cadavers in broad daylight. Even worse, the animals shown are clearly tame domestic ferrets, which are at least twice the size of a short-tailed weasel and don't look anything like them. And once again Hodges once more bare-handedly catches a wild animal that would run away long before he got near it or bite viciously if cornered.
Early in the episode we're told that the victim's cortisol levels are low, so much so that he had to be enjoying whatever was happening to him at the moment he was killed. This leads them to a chain of inquiry that reveals the victim was into S&M and therefore not feeling threatened when he died. Given what we later discover about the exact circumstances of his death, however, the cortisol levels could not be so low.
