Born October 18 at Switzerland's Zoo Basel, three baby African Ground Squirrels are already living up to their squirrelly reputation as keepers struggle to prepare them for transport to their new home at the Frankfurt Zoo. Together with their parents, they have built an elaborate series of underground tunnels beneath their enclosure. When they are alarmed, they quickly dart back into their tunnels making it impossible for keepers to reach them. 

While the sex of the squirrel pups has yet to be determined, they all appear happy and healthy. One of the pups is smaller and shyer than the rest, but keepers have made a special effort to feed him or her individually, and the frenetic critter is doing just fine.
