Methodology

Cage size standards

We recommend a minimum of 4,000 cm² (≈ 620 sq in) of unbroken floor space for all hamster species, exceeding the German Tierschutzgesetz baseline and most welfare-organization guidelines.

Bedding depth

We recommend a minimum 15–25 cm bedding depth so hamsters can build true burrows. Visualize the impact using the bedding depth tool on our homepage.

Wheel sizing

Syrians: minimum 28 cm (11 in). Dwarfs & Chinese: minimum 21 cm (8 in). The hamster’s back must remain flat while running.

Bedding safety

We never recommend pine or cedar shavings, scented bedding, or fluffy synthetic nesting material. Paper, aspen, and kiln-dried softwood are safe.
