What to do if your hamster escaped from its cage?

Put the cage on the floor and leave it open. Put a few treats in each room of your house. Then check on it everyday. At night listen for noices. We had 3 of our hamsters get out and they all came back. I just let it go and they showed up. My hamster got out a few weeks ago and i couldn't put the cage on the floor because there was another hamster in the cage. But i found her about 4 days later behind my frige.
