How to tell male and female cats apart
In the process of raising cats, many pet owners may be curious about how to distinguish between male and female cats. Although it is relatively difficult to tell the sex of a kitten, it can still be determined accurately by observing a few key characteristics. This article will detail how to distinguish male and female cats based on appearance and behavioral characteristics, and provide structured data for easy reference.
1. Distinguishing appearance characteristics

The gender of a cat can be initially judged by its appearance, especially for adult cats. Here are the main differences in appearance between male and female cats:
| Features | male cat | female cat |
|---|---|---|
| body shape | Typically larger and more muscular | Relatively small and slender |
| head | The head is wider and the cheeks are fuller | The head is narrower and the face is more pointed |
| genitals | The distance between the anus and the genitals is far, and the testicles are visible (in adulthood) | The anus and genitals are close together and form a straight line |

Sexing kittens can be difficult, especially within the first few weeks of life. The following are the key points for distinguishing the gender of kittens:
| age | Male cat characteristics | Female cat characteristics |
|---|---|---|
| 1-2 weeks after birth | The genitals are far away from the anus and are shaped like small dots. | The genitals and anus are close together and form a line |
| 3-4 weeks | The testicles begin to develop but do not droop significantly | The vulva is flat |
| 6-8 weeks | The testicles gradually become more obvious and may sag slightly | The vulva remains flat |
3. Differentiation of behavioral characteristics

| behavior | male cat | female cat |
|---|---|---|
| territoriality | Stronger, likes to mark territory | relatively weak |
| Activity level | More active and like to explore | Relatively quiet and more dependent on the owner |
| Estrus performance | Will call frequently and try to go out | Will show more obvious agitation and clingy behavior |
