How do I catch a escaped hamster?
Most times a hamster will come back to their cage on their own. Place the cage open on the floor (with a supply of fresh food), near its usual location. Leave it over night since Hamsters are nocturnal. Then check in the morning for your little runaway.
If this doesn't work you can try locating you little one by setting up a small pile of counted sunflower seeds in each room. Then count them in the morning. If he is still around he will be drawn to the food. Once you have narrowed down the room try setting up his home in there and wait once again. If you like you can wait up (you have to be very quiet) to close the door behind your hammy or check back in the morning to see if he is home.
