How deep should hamster bedding be, and which cages handle it?

Owners generally aim for 6 inches or more of bedding to allow natural burrowing, and the taller 20-inch-plus enclosures here are favored because they accommodate it. Note the recurring caution that very deep bedding can bow or pop the acrylic side panels out on some BUCATSTATE 2.0 units, so check panel seating after filling.
