 Here are some happy vampire 1 bats. What's causing all this giddiness? A great, big, fat meal has arrived. You can practically hear these bats going "Oh, boy! Oh, boy!" Better yet, the victim is asleep. This is gonna be like, well, taking blood from a sleeping pig.


 
The bats have heat sensors 2 in their noses. This thermal 3 process lets us see what the bat sees. The bat wants to feed where the pig's skin glows white hot. Let the dining commence. Like two wildcatters fighting over a fresh oil strike, these bats battle over a particularly rich feeding spot. Four vampire bats, one sleeping pig. Why doesn't the pig wake up? Because the bat's teeth are razor-sharp and cut painlessly. The bats can sip 4 to their hearts' content with the pig none the wiser. The bat's saliva 5 actually prevents the blood from clotting 6. As the bat sips 7, the blood runs up a glue on the underside of its tongue. Mother Nature thinks out everything. These vampire bats can feast for a full half hour, drinking half their weight in blood.
 
In a month of feedings, five vampire bats can guzzle 8 almost a gallon of pig's blood. In this case, it's the bats making a pig of themselves, not the pig.
