KIDS ASK: Do Bats Have Lots of Young Like Mice?

Unlike mice, bats are among the slowst reproducing animals on earth. And bats are actually more closely related to humans than they are to mice. Female bats start having pups when they are 2 to 3 years old.  Mice can start reproducing when they are 3 to 4 weeks old.  Bats usually give birth to only one pup a year. Mice have litters of from 10 to 20 pups at a time. Newborn bat pups weigh one third of their adult weight. Like mice and other mammals though, a bat pup drinks milk until it can find food on its own. The lifespan of a mouse is about 18 months,  but bats can live from 24 to 40 years!
