Signs Your Guinea Pig is Pregnant

Now that we’ve answered some basic guinea pig pregnancy questions, we’re going to go through the signs of pregnancy in guinea pigs. Early on, there aren’t many, but if you know your piggy’s habits well, you might be able to tell.

Gaining Weight

The first physical sign of pregnancy will be weight gain. You may not be able to tell right away just by looking at your guinea pig, though. If you have the habit of weighing her daily (maybe you’re keeping an eye out for pregnancy), you will notice it early on as just a few grams of weight gain each day. But by the time they are ready to give birth, they may have doubled in weight.

Eating and Drinking More

Of course, weight gain happens when your guinea pig eats more. This may be one of your first indicators of pregnancy. If you give your piggy a varied diet of pellets, fruits and veggies, she may favor the vitamin C-rich ones while pregnant, as they need more of this nutrient during this time.Another sign of pregnancy is drinking more water. You may notice that you have to refill the water bottle more often than usual, and this could mean little ones are on the way.Take care that your guinea pig doesn’t eat too much and gain too much weight during pregnancy. Toxaemia is common in guinea pig pregnancies, and overweight sows are more at risk. This can happen in first and second pregnancies.

Larger Abdomen

At first, you won’t be able to tell the difference in your pregnant guinea pig’s growing belly. Later on in the pregnancy (by day 50-60), though, you will notice that the abdomen is getting bigger. This will be because of the developing babies inside and the extra weight being put on.

You Can Feel the Babies

Sometimes in pregnant guinea pigs, you can actually feel the miniature piglets forming inside of the mother. With one hand and without applying pressure, gently feel the sides of your sow. If there are piglets, you will be able to feel little lumps. This can also be done by gently holding your piggy by the shoulders with one hand and feeling her belly with the other.If you do feel lumps, it would be wise to take your guinea pig to the vet to check for pregnancy. If she is not pregnant and has lumps, it could mean a serious health problem. Either way, it’s a good idea for your vet to check it out in either case.

Widening Pelvis

Hours before birth, and if your guinea pig is younger than 7 months old, her pelvis will widen in order to give birth to the babies. It should get at least an inch wide, maybe wider. Like we previously mentioned, if your sow is older than 7 months, you will need to take caution and likely have your guinea pig go through a cesarean section.

Next Steps

Now that you are almost sure your guinea pig is pregnant, you will need to do a few things to make sure she has a healthy and smooth pregnancy:The first step when you suspect pregnancy is to take your piggy to a vet that specializes in small rodents.

In addition to refilling her water bottle with fresh water daily, you will need to provide her with nutritious food like grass hay, leafy veggies, fruits rich in vitamin C, high-quality pellets, and, if you’d like, lucerne hay for an extra protein boost.Once the babies are born, it’s a good idea to separate the dad from the mom and babies right away. This is because your sow can get pregnant almost immediately after birth, which would mean back-to-back pregnancies for her and could be hard on her health.Also, the babies reach sexual maturity early too, so it’s possible for the dad to impregnate the female babies. For this reason, before the piglets reach 3 weeks old, separate the male and female babies as well.
