How Can I Tell the Sex of a Kitten or Cat?

By Alberto Roy

Published on:

It can be difficult to tell a male cat from his female, and it is even harder to sex a kitten with a male. However, there are certain signs and behaviors that make it easier for you to tell if your cat is having sex. Let us brainstorm about sex of a kitten in the blog post.

If a kitten or cat has been successfully sexed and the owner is not a cat breeder, it is important to find a vet who can spay/neuter the pet.

Sexing Kittens

Chances are that a kitten you adopt is just a few weeks old. Tiny kittens and newborns are often so young that it is almost impossible to tell if they are having sex.

Their genitalia will become more visible after they are six to eight weeks old.

However, the penis isn’t normally visible in male cats and it’s unlikely the owner will be capable of feeling or seeing the scrotum.

Therefore, a kitten’s apparent absence of testes or penis is not a sign that it is female.

Why do cats purr?

Breeders use “punctuation markings” to identify the sex of neutered or younger cats.

Begin by gently raising the pet’s tail. Then, gently stroke the lower back of the cat.

  • Female cats When you look at the genital area of a female cat, the area just below her tail, it will look almost like an upside-down exclamation point ( !), with the long slit in the vaginal area beneath the anus.The distance between the anus and vagina is usually less than half an inch. The anus and vagina can look similar in kittens.
  • Male cats The male cat has a greater separation between the anus (male) and the penis (male), with the testicles at the center. These openings are more like circles, dots, or colons (:), than slits and lines.

Sexing Grown Cats

If you are adopting a mature cat, the same sexing techniques as for kittens should be used. This usually works well for both neutered or “whole” cats.

It’s easier to determine sex of a pet if they are not spayed/neutered if the appearance is as good as their behavior.

There is no apparent behavior difference between genders once cats have been spayed or neutered. However, differences in behavior are likely to be due to individual cat temperaments.

  • “Whole” cats Tom cats who have not been neutered will have clearly visible testicles and a larger jowl. As they grow up, their unique behavior patterns begin. Male cats that are not neutered tend to be more aggressive and active than those with a female.

    Also, they are more likely to mark their territory with urine spraying than neutered kittens. If a female cat has not been spayed, she will enter heat approximately every two weeks.

    As she tries to find a partner, her behavior may change dramatically. Un-syaped female cats tend to be more vocal and demanding during this period.

  • Spayed and neutered cats. Spayed female cats will still display the upside-down “!,”, but if she is to be adopted as an adult, xrays or an abdominal ultrasound may need to be taken to confirm that she has been spayed.

    It is important to determine if female cats have been spayed before they have an unplanned litter.

    The vestigial remnants from a testicle sac will remain in most neutered male cats, although the anus will be fairly close to the penis.

    The typical behaviors of neutered cats are not male or female.The passive nature of neutered males is generally greater than that of “whole” males. Spayed females don’t go into heat.

Differences in Appearance

Although all cats are very similar in appearance, certain colors and physical signs are specific to one gender.

It is very rare for male cats to have tri-colored tortoiseshell or orange-and black calico fur. If you have a tortie or calico cat, there is a good chance that your pet is a male.

Rarely will a female cat have orange-colored or ginger-colored fur (or orange-and white striped). If your cat is orange, it’s very likely that it’s a male.

Cats that have given birth are more likely to have visible nipples, though both males as well as females can have them.

Vaginal discharge may occur in heat-prone females. Pregnant cats will often have a distended, low-hanging belly.

Call your veterinarian immediately if you suspect that your pet may be sick. Your veterinarian is the best person to consult for health questions. They have seen your pet and know your pet’s history.

How do you see a cat penis?

You wanted to know how to determine the sex of a cat after he has been neutered. Janis, this can be tricky. This is especially true for kittens. It is easy to tell if a dog has a male or female side by side.

The penis will be found under the dog’s belly, and he will urinate there. Females have a urethra just below their rectum, and they will urinate there.

There is a difference between cats and dogs, but it can be difficult to see. Cats don’t like to be still during these “inspections”, making it even more challenging.

It is possible to tell the difference, so that answer will suffice. The only thing that has been removed from a male cat’s penis is his testicles.

You can see the penis of a cat. To do this, locate the area where his urethra would exit. It’s under his tail. Below is the rectum.

You will generally see a small tuft of hair in the middle. This is his penis. The penis must be protruded by the owner. This is something that cat owners don’t see. They keep it hidden away.

It may be easier to just take your vet’s word that he is male.

Your Cat has a Clitoris and 5 Other Things You Don’t Know about Cat Genitalia

One day, as I was contemplating the wonders of the reproductive system and how we differ from others, the thought occurred to my mind, “Hmm… I wonder, cats have aclitoris?” Being a science geek, I decided to search for the answer.

I was soon entangled in a web of amazing and bizarre facts about cat genitalia. I couldn’t wait to share them with you, because I am such a geek! Here are some things I learned about cat’s genitalia. You have many questions about cat gentialia, admit it.

1. A male cat’s penis has barbs

The penis of intact male cats has rows of small, pointed barbs that point backwards at the head. The barbs disappear when a male cat has been neutered.

2. Yes, cats have clitoris.

A female cat’s internal clitoris, like most mammals, is located on its inside. Although it is located close to the opening of a cat’s vagina, it is not as visible as the human clitoris.

Knowing the exact location of the clitoris, however, I cannot help but think that the penile barbs can cause pain like none I have ever experienced.

3. Female cats have an Y-shaped uterus.

Two “horns” are found on the main body of a cat’s uterus. These horns are used to grow kittens. Each kitten’s placenta and the developing kitten is kept in place by an allantois-chorion, a special sac that holds them together as they grow.

4. A penis bone is a part of male cats.

Most placental mammals actually have a penis bone. This bone is also known as the “baculum” (Latin for “stick”, or “staff”) and helps keep the penis in place for as long as possible.

5. Cats don’t ovulate unless they mate

A female cat that is in heat can mate but she won’t release eggs until after mating.

Current research suggests that ovulation is caused by the pain the tomcat feels when he pulls out his penis.

6. Cats’ penises face backwards

The cat’s penis is in its normal state. It faces towards the tail. The penis is not able to extend much further forward even when it’s erect.

This and the fact that a male tomcat’s fully-erect penis measures only two inches in length, are likely the reasons why the female cat adopts an upright position during mating. She is doing her best to allow the male cat to access her vagina.

Why is a Male Cat’s Penis Barbeted?

Each physical trait your cat has is important for survival. The penis barbs of a male cat are not an exception.

They ensure his genes are passed down through successful mating. They are not something he was born with, and if he was not neutered young enough, he might never develop them.

Cats aren’t born with them

Barbed penises are not given to male kittens. Mar Vista Animal Medical Center in California says that cats reach puberty at 6 months. Because they are intended to assist in reproduction, the barbs form on the penis. Female cats are sexually mature.

Stimulating Ovulation

The barbs on a cat’s penis are there to assist in female ovulation. Females do not ovulate before sexual intercourse.

Instead, the barbs stimulate the vulva of the female cat during intercourse and cause her body to release an egg. Although painful for the female, this is part of the process.

Preventing the Female from Escaping

Barbs are placed on the penis of cats to prevent the female cat escaping before the mating process is completed. Because cats are more likely than dogs to be lonely, they may try to flee.

Mating can be painful for female cats because of the barbs and the fact that the male cat starts by biting the female’s neck.

Early Neutering Prevents the Development

Mar Vista Animal Medical Center claims that male cats that are neutered before 6 months of age never get barbs on their penis.

The procedure of neutering involves the removal or replacement of the testicles. This stops the cat from developing its reproductive organs. It is best to do it before the cat turns puberty. This will prevent the penis from developing barbs.

Before changing the diet, medication, and/or physical activity of your pet, always consult your veterinarian. This information does not replace a veterinarian’s opinion.

What age are cats sexually mature?

Kittens are adorable, tiny, and fluffy creatures that will grow up quickly. Your kitten can grow up in a matter of seconds from an infant to a fully grown adult capable of reproducing. Find out how to recognize signs that your feline is sexually mature.

Female Cats

The average age of female cats, also called queen cats, is 6 months. However, it can vary from one case to the next. It can take as little as 4 months for early bloomers.

It can take as long as one year for late ones. Queens are at reproductive maturity when they start their heat cycles.

They are often vocal and ready to mate during heat. You can tell heat by their persistent, loud yowling, their unusually affectionate, tactile behavior, and repeated attempts to escape. You and your neighbors will likely notice that your cat is experiencing heat.

Male Cats

Tomcats are male cats. They can become sexually mature in the same time-frame as queens — around 5 to 6 months. Although male cats don’t have heat cycles, they are vocal about their desire to mate.

A male cat that is sexually mature will yowl and meow constantly, use territorial urine spraying and run away from other cats, and be prone to wandering and wandering.

The most unpleasant and obvious sign is the urine marking. This is the tomcat’s way to lure in nearby females.

Spaying and Neutering

Many hospitals and clinics are increasingly able to spay and neuter very young kittens. According to the ASPCA, spaying kittens as young as six to eight weeks old is a routine procedure.

Cats are not yet close to sexual maturity at this time. This prevents cats reproducing in the future and also eliminates the stressed behavior patterns.

It also stops female cats experiencing the discomfort that comes with having a litter of kittens.


Both male and female cats can reproduce at just months of age, but most breeding practices delay this until they are older.

Cats are usually around 18 months old when they begin the process.

You don’t have to breed your cats. Instead, adopt kittens from a shelter and prevent overpopulation. It will make your fluffy friends very happy.

Before changing the diet, medication, and/or physical activity of your pet, always consult your veterinarian. This information does not replace a veterinarian’s opinion.
