For a Roborovski hamster, the single most important consideration when choosing a playpen is bar spacing. These tiny, fast hamsters can squeeze through gaps larger than 1/4 inch, so a playpen with narrow bar spacing or solid walls is essential to prevent escapes. Our editorial team has compared top options to help you find a safe, secure space for your robo to explore.

Roborovski hamsters are the smallest and fastest of the dwarf hamsters, so they need a playpen with high walls (at least 12 inches) to prevent jumping or climbing out. Look for materials that are easy to clean and chew-resistant, as robos may gnaw on plastic or wire. We recommend avoiding mesh or widely spaced bars, which can cause injury or escape.
