Determining the might be difficult—even specialists have trouble telling a female cat from a male at first appearance. However, a few distinguishing characteristics, such as genital spacing, coat color, and temperament, may be seen in kittens as early as five weeks old, identifying their sex.
Within the first several weeks of life, don't interrupt the mother-kitten bond. If a kitten is handled excessively during this period, the mother may forsake it and cease feeding it entirely. So don't be too concerned with determining the gender of your kittens. Instead, wait until your kittens are at least two weeks old, ideally longer.
It's important to be calm while determining your kitten's gender. Pick them up and softly touch them while hugging them close to your body. Scratching their back around the base of the tail may force it to rise, giving you a bird's eye view of the sections in issue. If a kitten appears aloof or nervous, postpone the examination and focus your attention on a less sensitive littermate instead.
Identifying the Genitals
Some breeders compare the look of kitten genitalia at two weeks old to punctuation marks. The vertical vaginal slit sits right below the anus and there is very little space between the genitals of a female kitten, like an upside-down exclamation point (when the cat is upside down and facing you). The penis is located slightly below the anus and separated by enough room to accommodate his testicles in a male kitten's organ, which resembles a colon. Small lumps may be visible in that region, which will expand as the cat matures.
If every kitten appears to you to be the same, choose one and gently place your finger and thumb on either side of the scrotum area (on a suspected boy). Under the skin, palpate two tiny, firm, oval-shaped items. The testes are almost tough to grip because they slither away beneath your fingertips. If testes are present, your kitten is clearly male.
The color of your kitten's coat is another easier, but less consistent, way to determine its sex. Almost all tortoiseshell or tri-colored cats are female. Because the chromosomal composition of female cats is entirely responsible for this colouring, every calico cat is almost always a girl. Orange or ginger-colored cats, on the other hand, are almost always male (think of the iconic male tabby cats). Only three-quarters of ginger-colored cats are male, making this characteristic less dependable than the tri-colored trait.
As kittens get older, they begin to acquire their own distinct personalities. As they reach sexual maturity, male "tom kittens" may begin to wander. They may also become territorial, to mark their territory and warn off intruders. Males are also more agitated and violent than females.
Female kittens as young as four months old may go into heat, announcing their "coming of age" with loud yowls and attention-seeking behavior. The earlier you spay or neuter your kitten (the conventional advice is five to six months, although pediatric spay and neuter can happen as early as six to eight weeks), the less gender subtleties your cat will exhibit.
Male cats are said to be nicer and more extroverted than female cats. However, this distinction is far from ubiquitous, and cat personalities are almost as diverse as human personalities. So pick your pet based on the initial connection you have with it, rather than its gender.
