Basic Guide

Cavies have to be under 9 months when first bred from because their pelvic bones fuse together and they will have difficulty giving birth. When you mate up a cavies you can put the boar in the the sow or vice versa. It is common practise with breeders to put in a boar with a large group of sows. Cavies come into season every 2 weeks so leave the boar in with the sow for 1 month to ensure that she has taken. Remove the boar before the sow/s give birth as it is quite common for the boar to remate the sow after she has given birth as she is extremely fertile.

Cavies will carry for around two months. Young cavies are born fully furred and are eating within a few hours of been born and they look like Miniature versions of their mothers. Leave the baby guinea pigs with the mother for about 6 weeks before separating them as the young boar/s are "active" at a young age.
