Rats are pregnant for about 21 days. At about day 14 the rat’s nipples will enlarge and darken in color and the rat will start to make a nest. On days 18-21 the rat will give birth to 6-12 young. The young are born blind and hairless and will weigh about 10 grams each.
Rats are able to become pregnant again within days of giving birth so it is important to provide them with a safe place to nest and raise their young. If you have rats as pets it is also important to provide them with plenty of toys and stimulation as they can become bored and destructive if left alone for too long.
