Unusual friends

This is cute:

A rodent-eating snake and a hamster have developed an unusual bond at a zoo in the Japanese capital, Tokyo. Their relationship began in October last year, when zookeepers presented the hamster to the snake as a meal.

The rat snake, however, refused to eat the rodent. The two now share a cage, and the hamster sometimes falls asleep sitting on top of his natural foe.

I bet it's hard to cuddle though.
