What should the depth of my hamster bedding be?
Ideally, for a standard hamster, you want to fill the bottom of their hamster cage with around 6 inches of bedding (otherwise known as substrate). This depth will allow them to be able to burrow into the ground, as comes naturally to them. Additionally, hamsters like to build their nests up using materials they find. Providing them with a decent depth of bedding will give them the means to do so without leaving any gaps.
