They drink blood but in Twilight they can also eat human food but cannot digest it so they have to cough it up later.
Seperate answer:
That is wrong vampires can digest humain food aslong as they have a sufficient amout of blood in thier system to be able to keep thier system running; otherwise they can become very sick and may go into a phase called Hibernation if thier not careful.
Vampires occupy a whole spectrum of types and abilities.
* Anything, just as an ordinary person * Specialty foods, those that deliver the most life-essence for their particular metabolism: fungus, plants, mold, carrion, meat, blood, fat, serum, * Nothing at all, steal life-force directly, with no intermediary.
Vampire bats feed using their mouths. This is the way that many animals feed off of their many food sources.
They eat insects.
vampire bats are blind and drink blood
They drink blood from cows
blood
Vampire bats eat/drink the blood of mammals such as deer.
because there is no connection between vampires and vampire bates just the name the name was given to the bat because they drink some blood but the bats don't feed off the energy the bat just drink the blood for food
Most small bats eat insects, and large fruit bats eat fruit. Central American vampire bats walk up to livestock, bite them, and lick several drops of their blood; bats do not drink blood.
Only vampire bats consume blood as their source of food. Other bats eat insects, amphibians, small animals and fruit.
it can be a fruit but not for a vampire bat it food is animal blood but not haman's blood
coz they cant eat other food....
Vampire bats eat/drink blood from other animals. With their sharp fangs, they cut into an animal, and to prevent the cut from scabbing/cutting off the bllod flow, the vampire bat spits into the cut, which keeps the blood flowing and also prevents the animal from feeling anything. But sometimes the vampire bats get too greedy,thus causing them to drink too much blood, making them un able to fly until the blood digests.
they suck blood off animals :)
Vampire bats usually bite then lap up the blood on sleepy out grazing animals.
do you drink period blood? I read about someone who fed their period blood to their boyfriend through food to try to change him into a vampire. Please, do not do that.
Ideally a vampire would not kill his food source but use it lightly for he/she would be assured of a continuing food source. If however a vampire wishes to create a new vampire then he would 'kill' his victim slowly assuring that the vampire contagin was in effect when the person died.
The Vampire Bats hunt for prey/food when it is completely dark and their diet is solely blood. Some species of Vampire Bats tend to feed mainly on birds while others feed on mammals.
