I've been pondering on this for some time I think we would all agree all hamsters are individuals and vary greatly in character but is it also possible that some are more domesticated and less likely to have the needs of what they would in the wild than others. How many wild hamsters run on a wheel they don't but for our pets it's essential they are perfectly happy running in circles and we provide enrichment I prefer to call it boredom breakers or toys we are just giving them things because they don't have to do what wild hamsters do and they seem happy with that because over the years they have been bred as pets not abducted from the wild is it the same as taking a wild dog into your home or buying a pet puppy and it automatically adapts to your lifestyle. Sorry for long post just food for thought.
