Kitti 's hog-nosed bat is the smallest species of bat and arguably the world 's smallest mammal . It has a reddish-brown or grey coat , with a distinctive pig-like snout . Colonies range greatly in size , with an average of 100 individuals per cave . The bat feeds during short activity periods in the evening and dawn , foraging around nearby forest areas for insects . Females give birth annually to a single offspring .
