I wonder if this was a Real Hampster:

BERLIN (Reuters) - A German man who went on holiday left his stereo and lights on so that his pet hamster would not feel lonely in the empty apartment, a police spokesman said on Monday after breaking into it over fears the man may have died.

The spokesman for police in Bremen said police broke open the door after being alerted by neighbors that loud music was playing non-stop for five days and the lights were left on. No one answered the door when they knocked, police said.

"There was a fear the occupant might have been disabled or dead," a police spokesman said. "All we found was a pet hamster. The occupant was away on holiday. A friend of his arrived and said he left the music on so the hamster wouldn't feel lonely."

The spokesman said the friend of the occupant, who is still on holiday and not reachable, told police she visited every few days to feed the golden hamster food and provide water. She promised to turn the music down and come by more often.
