Hamsters generally give birth to 2 to 13 babies per litter. The specific number depends on factors such as breed, age, health condition, and environmental conditions. Hamsters have a relatively strong reproductive ability. Usually, they can breed 2 to 4 litters per year, with an average of 5 to 8 pups per litter. Hamsters typically reach sexual maturity at 3 months old and start to be capable of breeding.
The gestation period of hamsters is 16 to 18 days. Baby hamsters can live independently at 3 to 4 weeks old. To ensure the success of breeding, it is necessary to provide hamsters with a safe, warm, humid, and well-ventilated environment and ensure an adequate supply of nutrition. In addition, to avoid the health risks associated with inbreeding, it is recommended to breed hamsters from different paternal lines.
