The minimum recommended cage size for hamsters is 80x50cm of unbroken floor space. Below is a selection of cages which meet or exceed these requirements. Most are also suitable for mice (some will need additional mesh adding if the bar spacing is wide). Where possible you should always seek to exceed the minimum size recommendations! Our favourite options for hamsters and mice are the Barney, Alexander and Detolf.
Most hamsters and mice will enjoy a wheel in their cage to run in. You should ensure it is large enough so that the animal does not have to arch their back when running in it:
Syrian hamsters – minimum wheel diameter 28cm
Dwarf hamsters & mice – minimum wheel diameter 20cm
Sawdust and woodshavings (unless the shavings are aspen-based) are not recommended as these can cause respiratory issues. Paper, cardboard, or hemp based bedding are suitable alternatives.
