Various cage accessories can be placed in a mouse's cage to provide extra stimulation and a more interesting environment for the mouse.

Houses

There are various "houses" for small pets and these are suitable for mice. It is important that any house has a ventilated top or open front to prevent condensation building within the house which can lead to the mouse and its bedding becoming damp.

Mouse Exercise Wheel

Many of the commercial mouse cages available today have exercise wheels fitted but there are also free standing wheels which can be placed in a cage or aquarium for those that don't.

Any wheel provided should have a solid back and a solid running surface. A mouse can slip on a wheel which has a runged running surface and if it gets its foot or tail caught between the rungs as the wheel is turning it can injure itself. Wheels which have open back/front with a bar across the diameter can also injure the mouse if the mouse should stick its head or tail out whilst running.
