Hamsters run on wheels for a surprisingly joyful reason
Hamsters and other rodents enjoy running on wheels for reasons beyond boredom or captivity. Research indicates that wild mice also engage in wheel running, suggesting it may be a natural behavior linked to their biology. The drive to run is likely connected to the reward centers in their brains, providing them with a sense of pleasure.
- ▪Wild mice have been observed running on wheels in their natural habitat, similar to captive hamsters.
- ▪Research shows that wheel running occurs voluntarily and continues even without food rewards.
- ▪Rodents are biologically suited for running, with faster metabolisms and larger home ranges than other animals.
