Some specific concerns with using Zhu pet accessories with Roborovski hamsters include:
* Small size: Roborovski hamsters are only about 2-4 inches long, so Zhu pet accessories may be too large for them to use safely.
* Sharp edges: Some Zhu pet accessories may have sharp edges that could cut or injure a Roborovski hamster.
* Toxic materials: Some Zhu pet accessories may be made with toxic materials that could be harmful to a Roborovski hamster if they chew on them.
For these reasons, it is best to avoid using Zhu pet accessories with Roborovski hamsters. Instead, choose pet accessories that are specifically designed for small rodents.
