How to read the male and female guinea pigs
Guinea pigs (guinea pigs) are a popular pet, but distinguishing males from females can be a challenge for many novice keepers. This article will explain in detail how to identify the gender of guinea pigs and provide structured data to help you quickly master this skill.
1. Appearance differences between male and female guinea pigs

There are some subtle differences in appearance between male and female guinea pigs, but these differences usually require careful observation to spot.
| Features | male guinea pig | female guinea pig |
|---|---|---|
| body shape | Usually larger and muscular | Small body, soft lines |
| head | The head is broad and well-defined | The head is rounded and has a soft outline |
| behavior | More active and likes to mark territory | Relatively docile and likes to live in groups |
2. How to identify reproductive organs
The most accurate way is to observe the reproductive organs of the guinea pig. The following are the specific identification steps:
1.Pick up the guinea pig gently, make sure it is in a relaxed state.
2.Observe the reproductive area: The reproductive organs of male guinea pigs are more obvious, while those of female guinea pigs are relatively hidden.
| Features | male guinea pig | female guinea pig |
|---|---|---|
| genital shape | There is an obvious protrusion of the penis | Y-shaped crack |
| distance | The distance between the genitals and anus is far | The genitals are closer to the anus |
3. The influence of age on gender identification
The gender characteristics of guinea pigs become more pronounced as they age. Determining the sex of young guinea pigs can be difficult, but the differences become clearer as adults.
| age stage | Male guinea pig characteristics | Female guinea pig characteristics |
|---|---|---|
| Infancy (1-3 months) | The genitals are small and the protrusion is not obvious | Flat genital area |
| Adult (over 3 months) | The genitals are obvious and the testicles may be drooping | The genital area is Y-shaped |
4. Common misunderstandings and precautions
1.Don’t judge gender based on behavior alone: While male guinea pigs are generally more active, female guinea pigs may exhibit similar behaviors.
2.Avoid excessive squeezing: When examining the reproductive organs, be gentle to avoid harming the guinea pig.
3.Consult a professional: If unsure, it is recommended to consult a veterinarian or an experienced breeder.
5. Feeding suggestions for male and female guinea pigs
After understanding the gender of guinea pigs, the feeding methods should also be adjusted:
| Feeding | male guinea pig | female guinea pig |
|---|---|---|
| cage size | Need more space (at least 0.7 square meters) | Can be slightly smaller (at least 0.5 square meters) |
| social needs | Recommended to be kept alone or paired with female guinea pigs | Can live in groups, but need to pay attention to group harmony |
Summary
Differentiating male and female guinea pigs requires patience and careful observation. You can more accurately determine the gender of your guinea pig by looking at the appearance, identifying the reproductive organs, and the influence of age.
