To breed your hamsters, start by housing the male and female hamster in separate cages to keep them from fighting. Once the female exhibits signs of being in heat, like crouching low and raising her tail, place her in the male’s cage since she’s likely to attack the male if he’s put into her cage. Additionally, put her into the cage in the evening, as hamsters are nocturnal animals. If the hamsters start fighting, remove the female immediately and try again the next day. After mating, keep the female in her own cage to prevent the male from attacking the babies. To learn more, like how to take care of the hamster babies once they’re born, keep reading!
