my first Hamster drown in a sump pump when the neighbors agreed to watch him while we went out of town. My best friend's brother forgot to put a weight on the snap-top lid to the cage (Mr. Magoo was a Houdini of sorts). Anyway, I was really young (probably 6), and the morning it happened, I woke up and had a feeling something was wrong. I walked down to my grandparents' kitchen (feeling nervous already), and my mom said my name in a strange tone-- I replied, "he's dead isn't he?" Did the same thing with a fish I had--so odd because it sounds like a movie, but it really happened! --it's amazing my parents didn't just toss me out the window right then and there for being the creepiest kid ever lol!
It was very sad though-- so maybe Cheerio was like, "hey, I have a plan, I'll just live long enough to compensate "lol
reportedly, there are other ancient hamsters out there as well (based on reddit etc- which, while not the most reliable source, it seems unlikely that someone would randomly lie about the age of their hamster lol!) I doubt I beat a record, ha!
