It depends. If the chinchilla is small than it is really risky. The male should be the same weight if not lighter than than the female. If the babies are to big it is risky. It is better not to breed just in case. But ask your chinchilla's vet.
A cat giving birth is called 'kitting'.
The Male chinchilla does not need to be there when and after she gives birth. It's suggested that if you have the male and female in the same cage to remove the male when she gives birth and have him in another cage neighboring her's. This is to ensure that the female does not become pregnant after just giving birth because it's very tiring for them.
The average amount of babies that chinchillas have are 2 but it can range from 1-6 babies. :P
