The situations under which it makes sense to separate gerbils are:
- After a surprise litter. Please see the section on surprise litters: by the time the first litter is discovered, the mother gerbil will be pregnant again, and the father should normally be left in to help raise the first litter.
- The gerbils fight
- When instructed by the vet due to contagious illness
- When separating a breeding male and female with a weaning litter
In all other situations, leave happy gerbils together. They love and need each other.
