Can a mother and daughter gerbil live together?

Yes, until they are at least six weeks old. You can even choose to leave the father in there, because he will help raise them by sitting on them and keeping them warm. Gerbils pups will depend on their mother for food until they are about 3 or 4 weeks old, at which point they will open their eyes, run around, and begin chewing on gerbil food and drinking from a water bottle. The pups should remain with their mothers even after they are weaned because they develop better social, grooming, and survival skills during this time. Most gerbil breeders will leave their pups with the mother for seven or eight weeks, but watch out for unwanted breeding during this time because a gerbil pup can become sexually mature by six weeks.
