Mouse lemurs live in holes in trees and are mainly nocturnal. They are quite like their distant relatives, the bush babies. They are the smallest primates. Although cuddly to look at, they are quite fierce and are reluctant to let go once they've bitten you. They have good hearing and store fat in their tails for hibernation. Two females may be pregnant and it is hoped that a colony can be established at London Zoo.
