Signs of pregnancy in guinea pigs may not be very clear. Therefore, those who live with guinea pigs should carefully monitor the changes in their pets. It is recommended that the diet of pregnant guinea pigs be meticulously planned. It is especially important that vitamin C and calcium supplements are not neglected throughout pregnancy. If the increased vitamin and mineral needs are not met, it may not be possible for the offspring to grow ideally. Common pregnancy signs in guinea pigs can be listed as follows: Increase in body weight Swelling of the teats Changes in behavior Changes in appetite Vaginal discharge As mentioned above, it is not always easy to understand the signs of pregnancy in guinea pigs. In fact, many pet owners only notice pregnancy in guinea pigs when labor begins. The gestation period in guinea pigs can vary between 59 and 72 days. Although each litter can produce a minimum of 1 and a maximum of 8 pups, the number of pups is usually between 2 and 4. Guinea pigs can give birth up to 5 times a year. A guinea pig can become pregnant again 2-15 hours after giving birth. During this short period of estrus after birth, if there are other male guinea pigs in the cage, fights may occur between them to gain dominance. The dominant male guinea pig will want to mate with the new mother guinea pig. Newborn pups weigh approximately 45-110 grams. It is extremely important to provide supplements to pups born weighing less than 40 grams. The weight of guinea pig pups should be monitored regularly, and a veterinarian should be consulted if the pups are not gaining weight. Although very small, the pups have fur, can see, and can even run within a few hours. They are fed with mother's milk for the first two days, after which they can also gnaw on solid food produced for guinea pigs. Pups continue to suckle on mother's milk for the first 3 weeks of their lives. During this process, they reach a weight of approximately 170 grams and switch to normal feeding.

It is recommended that female guinea pigs be introduced to as many different foods as possible in the post-birth period. During this period, the young also become familiar with the healthiest foods for themselves. When they consume only a few limited foods, the young may be reluctant to try new tastes later on, as they only learn about these foods. You can read our article titled "What Do Guinea Pigs Eat? Fresh Foods That Can Be Given" for detailed information about healthy foods for guinea pigs.

When the young are born, they are not fed for the first 12-24 hours. During this time, the mother and young should not be disturbed. When the young are 1-2 weeks old, they begin to urinate voluntarily. In the early stages, they are licked by their mothers to encourage them to urinate and defecate. Rejection behavior of the young can also be observed in mother guinea pigs. If the young are rejected in the first week, their chances of survival can drop to around 50%. In this case, it is necessary to seek support from veterinarians experienced in guinea pig health.

The Timing of the First Birth is Important in Guinea Pigs

The first pregnancy in guinea pigs should be planned at the right time. When a female guinea pig becomes pregnant at six months old, serious birth complications can arise. The main reason for this is the fusion of the pelvis, or pelvic bones. In this case, since a normal birth cannot occur, a cesarean section may become necessary.

There is another problem that can occur in the first or second births of guinea pigs: pregnancy toxemia. In addition to stress and obesity, limited mobility, starvation during pregnancy, many births, and advancing age can also result in pregnancy toxemia. Pregnancy toxemia can cause the end of the guinea pig's life without showing any symptoms. Symptoms include decreased appetite, reduced energy, avoidance of drinking water, muscle spasms, and lack of coordination. To prevent pregnancy toxemia, guinea pigs should be kept fit, stress should be avoided, they should have uninterrupted access to clean water, and they should be provided with healthy food.

Because female guinea pigs may have late first births or mothers too frequently, which is quite dangerous for their health, the option of sterilization may be considered. Sterilization of females is high-risk, therefore, support from experienced veterinarians should not be neglected.
