You can't see it in the picture because the cardboard packaging covers it, but on both sides of the wheel, there is a straight rod that stretches across the diameter of the wheel. The curved rods holding up the wheel attach to those straight rods in the center of each straight rod. At a certain point in the wheel's rotation, those 2 types of rods line up parallel. Last night our hamster appeared to have a broken back (& died hours later.) I wondered what the heck happened...and moments later, her brother hamster (in a separate cage with the same brand wheel) got stuck in his wheel. He entered the wheel up on the side a bit (not at the very bottom which is the safest entry point) when the two rods were coming together in sort of a triangle shape, then the rods moved to be nearly parallel, trapping him and squeezing him. He managed to wiggle free. But this had to be what killed his sister. The only other thing in her locked aquarium cage was a food dish, water bottle, igloo house, and carefresh paper bedding. Besides the unfortunate incident, I can say my hamsters use the wheels constantly in the night time, they love the exercise, and the wheels are very loud. I'm going to try to find a safer option for my remaining 2 hamster cages.

I have been operating a rattery in Michigan for over 8 years. The 11 inch mesh running wheel is the only wheel I use for my pets and I've tried every kind on the market. These are sturdy, a good price and my little fur friends have hours of fun running on these. The wire mesh allows them to grip their toes and really get some speed up. Usually two at a time can run on the wheel and one will stop running and hold on while the other keeps running, thus sending them flying up and over like a roller coaster. They'll take turns doing this. When they are babies you'll see six or more babies all running on the wheel at once with Mom providing the motion and all the babies hanging on with their toes to go flying up and over. They must really like the motion because they keep repeating this process like it's game or fun ride. I've raised over 1000 pet rats and never had a single injury with these wheels nor a single case of "bumble foot". I would recommend these wheels to anyone with a small pet. Oh, the other great thing about it they can see through them so they aren't looking through a brick wall like some of them and the poop and pee passes through so they aren't running in their own waste like they do with the solid plastic wheels.

Got this for my feeder mice, for something to do in their cage.

I've had pocket pets for 10 years. After trying about every wheel on the market in those years, this is the ONLY wheel I will ever use again! It is one of the safest out there (rating just behind comfort wheels) and it IS the quietest! If it squeaks, dab a little vasaline or veggie oil on it to make it completely silent again. Silent spinners, comfort wheels, etc don't hold a candle to these wheels! I've tried other wheels which imitate these wheels and found them to be very poor quality. They bend easily and literally fall apart. Run Around Wheels are of very good quality.
