Breeding Campbells Hamster

Campbells Hamsters become sexually mature at 5 weeks although it is recommended to wait until they are 3 months of age before their first litter. Gestation of 18-21 days with litter sizes around 4-6. The female can mate immediately after giving birth so male and female should be separated to prevent back-to-back litters.

They can be separated into same-sex pairs at 4 weeks to prevent inbreeding.
