What is false pregnancy in guinea pigs?
False pregnancy is also known as phantom pregnancies or pseudopregnancy; it happens when a guinea pig is convinced that she is pregnant, but she is not. It is common in any female guinea pig of breeding age.
According to a guinea pig, there is no difference between phantom and genuine pregnancy. She will behave like she is pregnant, although she is not.
What causes phantom pregnancies in guinea pigs?
It’s a misconception that is developed by the guinea pig, which lasts for approx 20 days. In some cases, it may last a little longer or shorter.
When female guinea pigs ovulate, she believes that she is pregnant, although she is not. Overstress can also be a reason for phantom pregnancies.
Let us understand this broadly.
- Overstressed: If a guinea pig gets stressed, they may ovulate, and then they create a misconception that they are pregnant. There are many ways your guinea pig can be stressed. For example:- Loud noises, Fear of predator, etc.
- Separated from a bonded friend: Guinea pigs can get stressed if separated from their bonded partner as they are very accustomed to their presence, and sudden vanishing of their partner can make them come into stress.
- Taken to the vet: Guinea pigs don’t enjoy medication and health checkups. A trip to the vet can definitely cause stress in your guinea pigs.
Will spaying prevent phantom pregnancies?
No, spaying will not prevent phantom pregnancies. Even after spaying guinea pigs can experience phantom pregnancies. However, there are many health benefits of spaying your guinea pigs.
Spaying a guinea pig won’t make her less attracted to the male; even an unneutered male will still mount a spayed female, which can result in phantom pregnancy.
So, we can say that spaying does not help prevent false pregnancy but it does provide health benefits to our guinea pigs.
What to do with the nest if your guinea pig have phantom pregnancy?
It would be suggested you not do anything with the nest.
Because if you try to remove the nest of guinea pig, there are chances that they might get upset and stressed.

How can u tell if a guinea pig is pregnant?
When a guinea pig experiences false pregnancy, they react as they are genuinely pregnant.
It also gets painful for us to decide by looking at their behavior because they have all symptoms which are there in pregnancy like mood swings, and overeating.
So, deciding about pregnancy on the basis of their behavior is not possible. Let’s discuss specific real pregnancy symptoms:
- Ballooning belly: When any female produces a baby, their belly gets to expand. So is with the female guinea pigs; when they get pregnant, they have an enlarged stomach.
- Eating more: It is prevalent to eat more at the time of pregnancy as there are 4-5 pubs inside guinea pigs stomach. The hunger level of your guinea pigs also increases as they require more food because they are eating for 4-5 babies.
- Mood Fluctuations: Even the sweetest guinea pig will become more volatile. Pregnancy leads to massive mood swings, which are the reason for anger in guinea pigs.
- Nesting: Whenever a guinea pig is pregnant, she will prepare a nest. Whenever you see your guinea pig carrying hay in her mouth for making a nest, you can consider it as a sign of pregnancy.
It will be challenging to determine whether she is pregnant or not, as she will have the same behavior as natural pregnancy.
She will engage in this behavior for at least 20-30 days, and after this, a phantom pregnancy comes to an abrupt halt, and guinea pigs return to normal.
There is an alternate way to check whether your guinea pig is pregnant or not.
You can move your finger around her belly, and while doing that, if you feel little lumps, then consider your guinea pig as pregnant.
If you don’t feel anything while moving fingers around her belly, then she is not pregnant.
