The female carries the young for about 24 days and gives birth to somewhere between 10 and 30 young, exceptionally even more.

Capital females also up to 100 pups. At birth, the pups are about 6mm in size. The young will grow quickly with good nutrition and quality water, let's not forget about ventilation.
