Big-eared Climbing Rat

Order: Rodentia
Family: Cricetidae


Conservation Status: Least Concern.

Newborn Big-eared Climbing Rats weigh about 10 g, or less than half an ounce. There are 1 to 4 in a litter. They open their eyes in less than a week, and a female was seen mating when she was not quite a month old. Adults have long, soft fur but almost hairless tails. They are nocturnal, eat mainly fruits and leaves, and forage on the ground and on vines and branches. They flourish in tropical forests, especially where there are rocks or rocky ledges.
