Heatstroke
From Sara
When I was a kid I got a hamster and my mom asked me to name it. I decided to name it Heatstroke. My mom said that was an unacceptable name for a pet and so it was renamed Heathcliff. Several months later it died of heatstroke.
A friend of mine has started a blog posting stories of how hamsters have died. You should check it out.
