How can I determine the gender of a kitten using pictures?

To determine the gender of a kitten using pictures, you can look at the distance between the anus and the genital opening. In male kittens, this distance is greater than in female kittens. Additionally, you can look for the presence of testicles in male kittens, which are usually visible as small bumps near the anus. In female kittens, the genital opening is usually closer to the anus and may appear as a small slit.
