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
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.
i think they sleep 10 hours
6 Hours of sleep is enough
they get 15 hours of sleep
Gerbils are nappers (as in they take naps throughout day and night). You probably just aren't there when the gerbil is awake.
6 to 9 hours a day.
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
