Comment on Common Vampire Bat by yellowmagpie.com.
Very few bats carry the rabbies virus. What’s more, very rarely will Vampire bats feed off humans. It is true that bats only survive for about two days if they don’t get blood. This is because blood is a very low energy food. However, bats feed each other. So if one bat is low on energy another bat will give it some of its food.
They only take about a spoonfull of blood at a single sitting.
Bats being this great blood thirsty monster figure is only literary licence used by folklore and cheap pulp fiction.
All in all I wouldn’t be too worried about a vampire bat! If you want more information about bats check out yellowmagpie.com/2009/07/bat/.
