"Are you GG or MM?" Do you guys still remember this popular social language?

In fact, this kind of trouble does not only occur on the Internet. It is also very common for cats to be indistinguishable from male to female. Adult cats are fine and can be easily distinguished by observing their balls. However, for some young cats, neutered cats, etc. How can cats tell the difference between men and women?

This kind of problem has been plaguing the cat owners. My friend’s cat recently gave birth to a litter of kittens, but the cat owner found that he couldn’t tell the male and female kittens. As a new grandfather, he couldn’t even tell the difference. It is actually quite confusing to not be able to tell the male and female of your own children.

　

So he found the happy cat and asked with a depressed look: It is so difficult to tell the difference between male and female kittens, how do everyone tell the difference?

In fact, it is not difficult to tell the gender of a cat as long as you do a few things well! Now, Xi Mao will give you a detailed science guide and teach you step by step how to tell the gender of a cat.

In fact, cats of different ages and conditions have different gender identification methods.

　

1. Genital judgment method.

In fact, whether it is a young cat or an adult cat, the genital judgment method is very useful.

　1. Young cats.

In fact, young cats are the most difficult to judge among all cats. They do not have mature secondary sexual characteristics, and the testicles of male cats are not exposed. Therefore, in general, young male cats and young female cats The secondary sexual characteristics of cats are actually not too obvious.

But is there no way to determine their gender? We can look for the cat’s external genitalia.

The distance between the genitals and anus.

First of all, we can find the cat’s anus. The part below the anus is the cat’s genitals. The feces scraper can judge the distance between the genitals and the anus to determine whether the cat is male or female.

Generally speaking, the genitals of a female cat are closer to the anus, about 1 cm, while the genitals of a male cat are farther than that of a female cat, and the urethral opening of a male cat is about 2.5 cm from the anus. distance.

Therefore, it is not difficult for us to find that if the urethral opening is farther from the cat’s anus, the cat is a male cat, and if the distance is closer, the cat is a female cat.

The shape of the anus and genitals.

The shape of a male cat is in the form of a ":" colon, while the shape of a female cat looks like an inverted "!" exclamation point, so overall, it is not difficult for us to see that as long as we observe the anus and genitals shape, you can determineCat's gender.

In fact, not only young cats, but adult cats can also use this method to observe the gender of cats. Of course, adult cats have a simpler way to determine the gender. I will talk about it in detail below.

　2. Adult cats.

Unneutered adult cats.

If it is an adult cat that has not been neutered, the judgment method is very simple, just see if the cat has two balls hanging on it! If there are, it means it is a male cat, if not, it is a female cat.

Of course, this method of judgment is not 100% correct. After all, there are still some male cats with cryptorchidism.

In fact, the original genital judgment method can also be applied to sterilized adult cats. In addition, sterilized male cats will actually still have a scrotum, but the scrotum will become flat. The cat can still find the scrotum as long as he observes carefully. The presence.

Some people may say that this method of determining the gender of a cat is good, but it is troublesome. Is there any simple and crude way to directly determine the gender of a cat?

Here I would like to recommend another method. Although it is not suitable for all cats, poop scrapers can also refer to it.

2. How to judge cat coat color.

The method of judging coat color is actually a little bit of unpopular knowledge unique to cats.

　1. Calico cats and tortoiseshell cats are almost all girls.

This is not just nonsense. According to statistics from an organization called the Humane Society, there is only one male cat in every 3,000 calico cats.

　

This includes some unpopular knowledge about cats. The color-producing gene for cats’ fur is the X chromosome. Let’s first review the biology knowledge from junior high school. We all know that females have two chromosomes, which are XX. Males also have two chromosomes called XY.

When a cat appears in three colors, it is usually black, red (orange), and white. Among them, black and red (orange) are the colors of the two X chromosomes. This Cats are usually female cats.

But we do not rule out the possibility of a genetic mutation in a male cat. When a male cat’s gene is XXY, it will also appear in three colors. However, we all know that the probability of genetic mutation and mutation is very small, so if it occurs Calico cats and tortoiseshell cats are basically small female cats.

If it’s a little male cat, then congratulations to you guys, you’ve found a treasure. The prototype of the Lucky Cat in Japan is a male calico cat. However, due to the mutation of sex chromosomes, male triflowers are almost devoid of fertility.

So if the cat owner discovers that there is a calico cat in the litter of kittens born to his own cat, then there is a high probability that it is a female cat.

​​​​​​

　2. Most orange cats are boys.

Of course, this probability is much smaller than the probability that a calico cat is a girl. After all, male calico cats are mutated, while orange cats are a matter of normal probability.

As mentioned above, the orange color gene is on the X chromosome. For male cats, as long as the X carries the orange gene, then its coat color must be orange. But if you want to ensure that a female cat is an orange, then you must ensure that the color genes carried on both X chromosomes are orange.

We can see the probability that there are far more male cats than female cats. According to incomplete statistics, the ratio of male cats to female cats among orange cats is about 3:1.

Therefore, if the poop scraper finds that there is an orange cat in a litter of kittens, it is more likely to be a male cat. However, it is not completely certain that the orange cat is a male cat. It still needs to be judged based on its genitals. method to judge.

In fact, there are many ways to judge whether a cat is male or female. The most complex and accurate method is the genital judgment method. If it is an adult cat that has not been neutered, looking directly at the balls is also a good choice. Of course, there are cats with special coat colors. Gender can be roughly determined by coat color.

So in fact, there are many ways to determine whether cats are male or female, so you might as well give it a try!
