How Can I Tell if My Rat is Pregnant?
As a rat owner, it’s critical to understand their reproductive cycle to provide them with the best possible care. Female rats reach sexual maturity around 4-5 weeks of age, and their gestation period is approximately 21-23 days. If you suspect your rat might be pregnant, it’s important to observe her behavior and physical characteristics closely.

- Increased abdominal size: The rat’s belly will gradually enlarge as the pregnancy progresses. This can be particularly noticeable if your rat is normally slim.
- Swelling of the mammary glands: The mammary glands, located along the rat’s underside, will become visibly swollen and pink.
- Weight gain: Pregnant rats will gain weight, especially in the latter stages of pregnancy. However, it’s important to note that weight gain can also be caused by other factors, such as obesity.
