Vampire bats are also surprising generous, willing to share a (regurgitated) meal with a fellow bat that missed out, even if they are not related.

Owing to its feeding habits the false vampire bat is acknowledged as a good friend of farmers and is rewarded with protection by farmers who call it the goddess Laxmi" and provide it food during harsh weather (Mahmood-ul-Hassan and Nameer 2006).
Greenhall (1972) observed that when a variety of hosts is present, the vampire bat is selective; although, when only the least preferred host is available, vampire bats may attack them severely (Turner, 1975; Voigt and Kelm, 2006).
He noted that vampire bats secreted multiple forms of the same active components, with myriad tiny changes scattered across the surface of the molecules and that even if an antibody is generated against one molecule, there are a number of other ones that will sneak past the prey's defence system and keep the blood flowing.
