Babies are always small...but who is the smallest? Could it be the otter cub swimming safely near the shore? The fuzzy bunnies cuddled next to each other? Maybe it's raccoon, with sharp claws to climb, or cute koala clinging to its mother's back. Or the owlets waiting patiently for food, or mischievous guinea pigs playing with balls of wool. No--the tiniest of all are the little mice so nice!
