GREAT FOR DWARF/REGULAR HAMSTERS, MICE, SUGAR GLIDERS, AND OTHER SMALL PETS Wodent Wheels feature a unique design with a safe solid running surface and a support stand without dangerous pinch areas. The only exercise wheel recommended and approved by the ASPCA during their Seal of Approval program (1999-2006). Rodents are attracted to the wheels entry holes, hamsters avoid broken legs and strangulations, and sugar gliders go absolutely nuts on these wheels. Even rats love running since they dont get their feet hurt and their tails whacked by unsafe axle supports. (Give ratties lots of time ? theyre very cautious!) The semi-enclosed design and the solid rear wall also makes rodents, who are natural “wall-huggers,” feel much safer as they run. Wodent Wheels are easily disassembled for cleaning and are constructed of tough, safe plastic with a stable base of heavy-gauge painted (baked-on powder coated) steel. Wodent Wheels are low cost, much safer and quieter than conventional wire exercise wheels, and have a clean, simple design using recycled and recyclable plastics. (NOTE: Wodent Wheels are not recommended for gerbils, chinchillas and most degus due to chewing problems. Not all are chewers and your mileage may vary ? but youve been warned! If you decide safety is paramount and youll live with the chewing, replacement front panels are available). Wodent Wheel Jr. 8" diameter, 2.6" wide, 2.1" entry holes. Overall height 9.1".
