What strange bedfellows! Gohan the hamster and Aochan the snake are roommates at Mutsugoro Okoku Zoo, on the outskirts of Tokyo. Gohan is a 9-centimeter-long dwarf mouse; Aochan, a 120-centimeter-long ratsnake. Zoo keepers had presented the hamster to Aochan as a tasty morsel in October, after the snake had refused to eat frozen mice. Instead of indulging, Aochan made friends with the furry rodent, according to keeper Kazuya Yamamoto. The pair have shared a cage since.
