Bats

Bats account for around 25% of all mammal species. As mammals, bats nurse their babies. Thailand's bumblebee bat, weighing less than a penny, is the world's smallest mammal. Some flying-fox bats of the Tropics have wingspans of up to 6 feet! Hundreds of plant species rely on bats to pollinate them. Like cats, bats spend lots of time grooming their fur.
