Hi everyone.. I'm quite new here.. Can ask? This actually happen 3 yrs ago..
I used to have 2 males + 1 female (regular drawf hamsters).. all siblings.. They continued to multiply and end up so many until gv away... (I know, kick me.. back then i didn't know bout inbreeding)
They all have since died of natural death.. lived up to 2 yrs++.. and my mom still feels sad cuz she misses them so much...

Out of the many litter.. Parents are grey and well.. dark grey.. the other sibling is brown.. came 1 very cute, all white red eyes male.. We had him for about 1week.. Then he started jumping like crazy inside the tank but he already did it for like 2 days so we thought he was fine.. So we went out for a few hours and went we came home.. he was dead..

The tank was clean, so much food and water.. got wheel to play.. the others were fine.. So my question is... can a hamster actually die from jumping too much?...I had a guinea pig which died from heart attack.. Can jumping lead to stress on the heart and cause heart attack?
