Rats can become pregnant at 6 weeks of age, which is why it’s a very good idea to separate them by gender by that time.

rats can become pregnant as early as four weeks of age. first breeding is not recommended until two months at the earliest.

Katt has it bang on.
Many times I've seen people buy a little rattie, get it home and a few weeks later there's a lot more than the one they bought.
