The Roll-A-Coaster is the spinning, rolling pet amusement park. The Roll-A-Coaster comes with a unique wheel that spins and rolls along the track, allowing small pets to quietly glide back and forth across the top of the cage in either direction. This habitat is as fun for owners to watch as it is for pets to play in. The Roll-A-Coaster also features a Second Story Loft, Petting Pod, Durable Food Dish, Wraparound Wire Wall, Lookout, Modular, Add-A-Feature Design and the Dwarf Hamster Tube especially made for extra small pets.
