Are all three cats female cats? No, the three-cat cat can also be a male cat. The three-cat cats are not necessarily all female cats, but the three-cat cats are very rare. Three-Katana cats have natural genetic defects. They both suffer from Kerry's syndrome and have two X chromosomes in their bodies. The probability of this genetic defect happening to cats is very small, so Three-Katana cats are very rare. There are only orange and black in the genes of the three-cat cat. White is the dominant gene, that is, white is the background color, and orange and black are based on white and supplemented with the three-cat cat. The gene that controls the color of the cat's fur exists on the XY chromosome of the cat, and this pair of chromosomes is a pair of chromosomes that determine the gender. It is called the sexual gene, also known as the sexual genetics. In genetics, the Y chromosome only exists in males, that is, the XX combination, the gender is female, and the gender obtained by the XY combination is male. When you get X from the female cat and X from the male cat, that is XX (that is, the female cat), which can carry information of one or two colors; when you get X from the female cat and Y from the male cat, that is XY (that is, the male cat), which can only carry information of one color.
So when you see the cat with orange and black colors, plus white, it must be a female cat, this is the three-cat cat. But male cats are not absolutely non-existent. There are still three cats and male cats in the world, but the number is very small.
