I was wondering : does a Desmodus dormicus imposes torpor on his victims? Is the victims core temperature dropped and there breathing slowed down to the point where they become cold-blooded and are completely dependent on the environment to wake up again. That would be convenient as they know that the victim stays asleep. But if so, the blood will coagulate and the Desmodus dormicus can not drink the blood anymore. It is a dilemma!
