How To Tell the Difference Between Male and Female Cats Easily

Are you wondering how to tell the difference between male and female cats? Telling the sex of cats is not as easy as many think, and it’s more complicated for a neutered male.

Identifying the sex of your cat, especially a kitten, is a useful skill to have. We mostly rely on physical appearance to identify a cat’s sex.

Just to give you a heads up, the distance between the anus and urinary opening is wider in male cats and shorter in female cats.

This is one of the most common physical traits that you can observe to determine your cat’s gender.

In other cases, you may need to ask your vet to confirm the gender, especially if certain physical features are unclear.

How To Tell If Kitten Is Male or Female

It can be difficult to accurately find the difference between male and female kittens, especially in the first few days of life.

In newborn kittens, the private parts are not fully developed. The difference between male and female kittens can be difficult to find.

As the kitten grows, in about six to eight weeks, it will be easier to see the difference, although it will still require careful observation.

In young male kittens, there is generally no visible penis, and the testicles may be too small to see or feel.

It is easy to assume the kitten is female if you look for a penis or visible testicles. Look instead at the spacing and shape of the openings under the tail.

Lift the tail; generally, a light scratch or stroke of the base of the back is all it takes to get the kitten to lift its tail themselves.

In a female kitten, the genital area is shaped like an upside-down exclamation mark. The anus is located directly above the vertical vulva slit, and the two are very close together.

In very young kittens, both openings may be small dots, but even so, the anus and vulva are still close together.

A male kitten has a larger space between the anus and the genital opening. Both openings are round, making the area look like a colon.

The space between them will eventually be occupied by testicles, whether they are visible yet or not.

How To Tell the Difference Between Male and Female Cats

Is my cat a boy or girl? This visual trick will also work on adult cats, both intact and neutered. Simply lift the tail and observe the differences in the appearance and spacing of the openings.

Neutered cats’ sexual characteristics will be less pronounced than those of their intact counterparts, but there are still distinctions to be made.

This is because the genitals of intact cats are in their prime, while hormones will also contribute to differences in their looks and behavior.

In an unneutered male, or tomcat, the testicles should be easily seen between the anus and penis.

In behavior, intact males are more likely to be high-energy, wander looking for mates, and spray urine to mark territory.

Unspayed females will go into heat cycles about every 2 weeks during breeding season. When she is in heat, she will likely be more vocal and active, and will constantly pursue attention.

In a spayed or neutered cat, the same gross anatomic features are visible. In a spayed female, the anus is still closely followed by a vertical slit (the vulva).

In a neutered male, a soft, empty scrotal sac often remains, and the distance from the anus to the penis is still greater than in the female.

The onset of sexual behavior, which may cause individuals to stray or fight, is suppressed by neutering/spaying since the necessary hormone surges do not occur.

It is best to have a vet technician do this if there is any doubt, for example, when the history of a cat you are adopting is unknown.

Male Vs Female Cat Anatomy

Male and female cats are mostly physically indistinguishable, but a few coat colors and slight body characteristics are associated with sex.

The most obvious is the coat pattern. Calico and tortoiseshell cats, which have patches of orange and black, are nearly always female.

This is because the genes for these colors are located on the X chromosome. Male calicos and torties are extremely rare, but usually sterile.

On the other hand, orange or ginger-colored coats – especially when solid orange or an orange-and-white tabby pattern – are more prevalent in males.

This is because the gene that codes for this color is located on the X chromosome, but since only one copy of the orange gene is required for this color to be present in a male, it is more likely to occur.

Females need two copies (one from each parent) for full expression as oranges.

Some other indicators are non-genetic and pertain to life experiences. Having kittens can lead to more pronounced nipples.

Being in heat can sometimes be accompanied by a small amount of clear or slightly cloudy discharge.

An obvious sign of a pregnant female, although it’s only in the later stages of gestation that the abdomen becomes rounded and hangs lower than a male cat’s, is a rounded belly.

Coat colors and reproductive indicators should be used only as clues; they are not definitive evidence.

How to Tell a Cat’s Gender by Their Facial Features

Male cat vs female cat face is another indicator of sex, but it is less reliable than visual examination under the tail.

The effects of testosterone in unneutered males sometimes cause the development of a slightly broader and squarer jaw and a more angular overall face.

This is due to increased bone structure and muscular development as the cat matures, especially in strong-jawed breeds.

By contrast, the overall facial shape of most females tends to be narrower, with softer facial angles and smoother outlines, which also affects their overall body shape.

These are, however, often not visible in kittens or spayed/neutered cats.

Male vs female cat face sexual differences may also occur in the whisker pad and in the shape of the snout. Male facial features include larger, more noticeable whisker pads.

These ‘tomcat cheeks’ give the male face a wider look. Their snout is typically longer, wider, and blunter, with a stronger bone structure.

The skull of a female is more delicate. The smaller whisker pads and shorter snout of the female allow her nose to taper more subtly into the rest of the face.

These differences are more pronounced when a male is fully mature and can be accentuated by breed.

Minor differences are sometimes visible in the forehead and neck. The male forehead can be flatter and broader, and the male neck thicker and more muscular, especially in an intact male.

The female cat usually has a rounder forehead and a slimmer neck. These traits may be of use in certain cases.

They should be used as supplementary observations in sexing cats, rather than as a method in and of itself. Physical examination is still the most reliable.

Choosing a Cat: Male vs. Female

Male vs female cat sex is likely to be one of the least important factors when deciding which one to adopt. Both males and females can show certain behavioral tendencies.

However, these distinctions are minimized once spayed or neutered, and in any case, not all cats conform to the typical mold.

A cat’s personality is determined much more by genetics, early socialization, and the environment you give them.

Two cats of the same sex can have different temperaments, and a cat of the opposite sex may be a better fit because of its unique personality.

Conclusion

The easiest way to tell if a cat is a boy or a girl is with a quick, gentle examination of the private parts under the tail.

Look for these two key indicators: distance and shape. For most cats, males will have more distance between the rectal and urinary opening, while female cats will have less.

In addition, the openings in male cats are more round, whereas the female cat’s openings are close together in a vertical slit.

Coat color or behavior may give you ideas on how to tell the difference between male and female cats, but these are just trends and not very reliable.

Don’t rush the process, especially with kittens who have less defined features or neutered males who may have changed physical appearance.
