No. Bats digest food virtually the same way that humans do. Like most carnivores they have relatively short, simple digestive systems. One thing that bats can do is to digest things VERY quickly. The little brown bat that is found over much of Canada can defecate as quickly as 30 minutes after eating a belly full of mosquitoes!
