The pangolin had been rampaging in her plastic box for the third night in a row and Isabell Stich decided, "It's time for Ping to move on." Ping, who arrived as a baby and has since grown considerably in size, with an urge for activity to match, had been living in Stich's and Kai-Olaf Krüger's guestroom for almost three months. But now she has her own territory - and is hardly ever seen. She likes spending her days sleeping in burrows that she never tires of digging again and again.
