My hamster slept for a week straight when it was new, eventually it will come out more often but
Remember they are nocturnal meaning they will sleep in the day. My hamster is now about 4 months old and awakes around five in the in afternoon.
Your hamster is asleep because it is a baby. As it gets older it starts to stay up during the day.
If your Hamster Is A Baby It Needs a lot of sleep. But If Its an adult it may be bored or it could be worn out if you play with it a lot or it has a big cage :)
Do you have any kinds of activities for your hamster to do like perhaps a wheel or something its like growing up if a person finds them selves bored with nothing to do most likely that person will just go to sleep.
It might be because during the day there might not be a lot of light so it feels like sleeping. And in the night there is no light at all so it sleeps.
My hamster has puffy cheeks, has been in his wheel for hours, he will run and run then stop and lay down in the wheel for about a minute. Then he starts up again.
Same here, the male dwarf hamster is always sleeping , but the female is up every 4-7hrs
