not very long they aren't like other rodent they dont sleep all day and are up all night at the most 1-2 hours a day otherwise u have a very lazy gerbil.
I sleep about 7 to 9 hours a day
they sleep about 3-6 hours a day
i think they sleep 10 hours
It is in a gerbil's nature to sleep alot. Although they are not strictly nocturnal, they can be as active in the day as they are in the night.
6 Hours of sleep is enough
they get 15 hours of sleep
6 to 9 hours a day.
Gerbils are nappers (as in they take naps throughout day and night). You probably just aren't there when the gerbil is awake.
19hours a day.
10 hours a day. In the winter they hibernate.
About 2 to 3 hours a day. Usually they stand when they sleep. They lock there legs to make them relax and they fall a sleep.
4 hours
