What is the Difference Between Male and Female Guinea Pigs?

There are several differences between male and female guinea pigs, which can be helpful to know when deciding which one to choose as a pet. Some of the main differences include:

1. Genitalia: In females, the genital opening is Y-shaped, while in males, it is more like an 'i' or upside-down. Male guinea pigs have a small bulge just above their anus, which is not present in females.
2. Size: Male guinea pigs are generally slightly larger than females.
3. Personality: Males tend to be more confident and self-assured, while females may be more nervous and take longer to form a bond with their owner. However, male guinea pigs can be more aggressive due to their territorial nature.
4. Social Needs: Males usually have different social needs, as they are more inquisitive and more willing to explore their surroundings.
5. Health: Unaltered male guinea pigs tend to deal with a condition called impaction more often than altered guinea pigs.
6. Smell: Female guinea pigs are often considered to be less smelly than males, as the grease gland in males can produce a stronger odor.
7. Lifespan: Males generally live longer than females, depending on their diet and care.

Ultimately, the choice between a male or female guinea pig depends on your personal preferences and the specific traits you are looking for in a pet. It is essential to consider these differences and consult with a veterinarian or rescue center if you are unsure about the sex of your guinea pig.
