Instructions

    • 1

      Place a male and female or a group of males and females together in a cage. When the female is ready, the male will mate with her. Usually, the male will mate several times in a row and this will increase the chance of pregnancy.

    • 2

      Watch the female after mating. If she gains weight, especially in her hind quarters, and begins building a nest, she's probably pregnant. Feed her food high in protein, such as peanut butter, cheese and oats.

    • 3

      Once you know she's pregnant, separate the male and female. This will keep her from getting pregnant again after giving birth, as she immediately goes into heat. Also, some males will eat the offspring.

    • 4

      Clean the cage a couple of days before she gives birth. The gestation period is 18 to 21 days.

    • 5

      Do not touch the babies for two weeks after they are born or the mother might eat them.
