No, the vast majority of tortoise shell cats are genetically and phenotypically female, as they need to have one brown gene on one x chromosome, and one ginger gene on the other chromosome. On very rare occasions, a phenotypic male tortoise shell cat will be born, but he is almost always sterile due to his genotype (XXY).

∙ 14y agoWell aparently all Tortoise Shell cats are Female. I used to have a Tortoise Shell and it was a girl so Im presuming they are all girls.
Yes they are in fact all girls. Also all ginger cats are boys.

∙ 14y agoNot always, but MOSTLY, yes. The chances of a male tortishell being born is about.........1 in 100, but tortishells themselves arn't very common, even the girl ones.
Wiki User
∙ 12y agoNot always, but it is very rare for a male cat to be tortoiseshell which is why you usually only see females.

∙ 14y agobecause the genes that give that coloring ar carried by the chromosome that determines female gender.

Are tortoiseshell cats female or male?
A tortoiseshell cat is a coat color where the cat is a molted brown cat with black, reddish, or orange patches. They can also have white paws. Tortoiseshell cats have unique genetics. The vast majority of tortoiseshell cats are female, because two X chromosomes are required to produce black, gold and orange coloring. Male cats only have one X and one Y chromosome, so technically it's genetically almost impossible for a male to inherit the tortoiseshell coloring. A male tortoiseshell has an extra X chromosome, making it an XXY. According to a study by the College of Veterinary Medicine at the University of Missouri, only 1 in 3000 tortoiseshell cats is male.

Where are tortoiseshell cats from?
Tortoiseshell describes a coat coloring found in cats. Cats of this color are mottled, with patches of red and black, chocolate, or cinnamon. They are sometimes called tortiesfor short. The term "tortoiseshell" (also called calimancoor clouded tiger in North America) is typically reserved for cats with brindled coats that have relatively few or no white markings. Those that are largely white with red and black patches (rather than a brindled aspect) are described as tortoiseshell-and-white (in the United Kingdom) or calico (in the United States). Tortoiseshells and calicos are not specific breeds of cat. The tortoiseshell markings appear in many different breeds.[1] This pattern is especially preferred in the Japanese Bobtail breed. Both calico and tortoiseshell cats are almost always female
Does a cat's coloring indicate gender?
Sort of. A Calico cat is almost always (99.9% of the time) going to be female. The reason is that the female has two X genes, one has to carry red and the other black to get the 3 color effect. For a male to be a calico, it has to have XXY and is normally sterile.

Are tortoiseshell cats friendly?
I have a tortoiseshell cat, and she is fairly friendly... well, she doesn't scratch me or bite me unless she is really freaked out, although she also tends not to like my younger sibling and her friends, but they're all really loud. I, however, can't speak for everyone, I'm sure there are some tortoiseshell cats that aren't friendly at all. 'Tortoiseshell' is just the color of their fur, I think there can be friendly and not so friendly tortoiseshell cats, but I know mine isn't mean.
Are all tortoiseshell cats girls?
Male tortie and calico cats are extremely rare. Here's a little feline genetics lesson: The reason is that black and orange hair can only occur together in the hair coat if that cat has two X chromosomes. Calico cats (white cats with patches of black and orange) and tortoiseshell cats (black and orange swirled together), therefore, have to have two X chromosomes, and two X's means that you're a girl.In order to be a boy, you need a Y chromosome. Boys are XY; girls are XX. Very rarely, a mutation occurs that leads to a calico or tortie male. Genetically, these cats are XXY. The two X's allows for the color; the Y allows for the maleness.The incidence is reported to be 1 in 3,000.In other words, out of every 3,000 cats with black and orange together in the hair coat, on average, 2,999 will be girls, and only one will be a boy. The XXY mutation leads to sterility. They can't reproduce. Your orange tabby girl is not sterile. Get her spayed.Fun Fact:Orange female cats are a little uncommon; only about 1 in 5 orange tabbies are female.
