Hamster, meet snake. Snake, hamster.

A dwarf hamster that was offered as a meal to a rat snake in Tokyo's Mutsugoro Okoku zoo has made friends with the snake, reports The Associated Press.

The zoo, which keeps mostly livestock animals, promotes "cross-breed interaction," says keeper Kazuya Yamamoto, but the Gohan-Aochan case "was a complete accident."
