Only hamster I've had was when I was about 13, the day after we brought it home from the pet shop it had several babies, we thought oh, got about ten for the price of one, then it went and ate them all, there were half eaten babies in the cage still alive, we had to destroy them.
Then a few weeks later it went missing, we searched high and low, down all the furniture, we couldn't find it anywhere, Then the following sunday, Mom was cooking the sunday dinner, with a chicken in the oven, she smelled a funny burning smell and opened the oven door to find the hamster at the edge of the door, instead of being a fluffy light tan it was burned brown and it's feet were burned of to the first joints on all four legs.
We bathed it in saline solution and put it back in it's cage, it recovered and lived about 18 months as normail, spinning it's wheel and everything.
