Are bats and flying squirrels mammals?

Yes, both bats and flying squirrels are mammals. Mammals are a class of animals that are warm-blooded, have fur or hair, give birth to live young, and produce milk to feed their young. Bats are the only mammals that can fly, and they use their wings to hunt for insects, fruit, and other food sources. Flying squirrels are rodents that have flaps of skin between their front and back legs that allow them to glide from tree to tree.
