Distinguishing between male and female adult cats is quite easy. Generally speaking, the genitals of male kittens appear round, and there is usually a small fleshy protrusion. In addition, the distance between their anus and genitals is more than 2 centimeters.

In contrast, female kittens' genitals are closer to their anus and appear as a straight line or teardrop. Additionally, the distance between their anus and genitals is approximately 1 centimeter.
