ANIMALS IN THE WILD LOVE TO RUN IN WHEELS
INCLUDING SLUGS AND FROGS
TOP: Experiment set-up (not a cage, open at both ends)
BOTTOM: Various animals use the running wheels, though mice are by far the most common. Stills taken from these recordings show examples of (b) a mouse, (c) a frog and (d) a slug using the wheel. (via Wheel running in the wild)

- Wheel running is often used in the laboratory for triggering enhanced activity levels.
- A common objection until now is that this behaviour is an artifact of captivity and merely signifies neurosis or stereotypy.
If wheel running is indeed caused by captive housing, wild mice are not expected to use a running wheel in nature. …. Here, we show that when running wheels are placed in nature, they are frequently used by wild mice, also when no extrinsic reward is provided. Bout lengths of running wheel behaviour in the wild match those for captive mice. (Wheel running in the wild)
