Extra large size gives hamsters, gerbils, and mice real room to run without hunching or dragging their back. Standard balls are too small for most adult hamsters.
Clear shell lets you watch your pet roll through every room. The classic hamster experience, properly sized.
Ventilation slots on all sides keep air flowing so your hamster stays cool and comfortable during long runs.
Snap-lock door closure stays shut while in use but opens easily for you to put your pet in or take them out.
Smooth interior with no sharp seams. Safe for bare paws on extended runs.
