Jason Price set some rat traps in a garage in Sonora. On one trap, there was a dead rat, with only the head left in the trap. All that was left was the head, and even the back of skull had been eaten away. In another trap was a large, big-bellied rat, un-eaten. Apparently the first rat was eaten by the second, and nobody was around to eat the second rat. We presume he was the cannibal rat. 30 October 2017.
