I use a toothbrush to brush Remington's fur, not sure why but I just thought it would be something he'd enjoy. He ignores it most of the time but sometimes...he does this (he may be small - but he is most definitely mighty and stronger than his tiny form leads you to believe):

Does anyone have a hamster with hoarding issues?
Anyhoo, it was too cute I had to share and I was intrigued by this odd behavior.
As far as personalities go - I would categorize Remi's as "Strong Personality" aka very opinionated.
