Gestation is generally 111 days. Females can become pregnant immediately following the birth of a litter. But these 'breed backs' are very draining and should only be allowed on a limited basis to females of excellent health. To prevent this from happening, the male should be removed from the cage for about seven days following the birth of a litter. Once reunited with their family, male chinchillas can make wonderful fathers.
Chinchillas can have one to six kits per litter, with two being average.
Young are born fully developed with fur, open eyes, and teeth. Weaning age is at about six to eight weeks, depending upon the overall development of the kits and the condition of the mother. Basic Chinchilla Care Chinchillas require the same basic care as most other pets, plus a little extra. Like any other animal, they need a source of clean water, proper food, and an appropriate place to live. Following is a short description of their basic necessities.
