Yes, it is normal for a rabbit doe's tummy to sag after giving birth to a large number of kits. The stretching of the abdominal muscles and skin during pregnancy and the process of giving birth can cause the doe's belly to appear loose or saggy. This is a natural occurrence and is not usually a cause for concern.

The degree of sagging can vary depending on factors such as the number of kits born, the size of the kits, and the individual doe's body structure. Some does may experience more pronounced sagging than others.

After giving birth, the doe's body will gradually return to its normal state as the uterus and abdominal muscles contract. It is important to provide the doe with a nutritious diet and proper care during the postpartum period to support her recovery.

If you have any concerns about the health or well-being of the rabbit doe or if you notice any unusual symptoms or complications, it is recommended to consult with a veterinarian who specializes in rabbit care for further evaluation and advice.
