Alright so I had three robo hamsters and I've had them for quite a long time. About five months. I cleaned their cages weekly and then freshened it up every few days and made sure they always had food. We went to clean out the cage today and one of the little girls was dead. I don't know why? They always had water and food, and I always made sure my room was a reasonable temperature. Do they not have a long life expectancy? I am just a little bit confused.
