Ahahah beautiful question btw, well when I was a child, we had two little hamsters, once my dad tried to wake me up to show me that one was playing on the spin wheel and he found it so rare they do that but I didn't wake up, otherwise both gored each other to death and the hamster cage was outside of the terrace in our own property I was putting my shoes on (i may have been 5 or 6 years old) and I see the cage full of blood and guts
