Have tu ever had a hámster that has gone into hibernation before?Mine did but we could not bring him out of it.Has hibernation ever effected your hamster?

he was still alive tho for a while, breathing shallow, and barely able to move. he did that a week hace too and all we had to do was warm him up and he was back to normal. the breeder called this hibernation.but this time we were not able to warm him. he eventually stopped breathing entirely.
