Hamster Fact: The wheel is a must if you keep hamsters. They can travel up to 3-5 miles in a single evening in the wild in search of food. It is best not to get the wire wheels as their little legs could fall through the rungs and get broken. Cases of the hamster getting caught up in the "pinch" areas and being strangled have been reported as well. The best wheel to get for your little guy is a Wodent Wheel. There are many sources for this wheel that you can Google, I got mine at the link above. Remember, No wire coat hangers! I mean wheels!
