are male calico cats sterile

All but approximately one in three thousand of the rare calico or tortoiseshell male cats are sterile because of the chromosome abnormality and breeders reject any exceptions for stud purposes because they generally are of poor physical quality and fertility.

What Factors Contribute to the Occurrence of Male Calico Cats?

Male calico cats occur because of genetic mutations. These include chromosomal abnormalities such as Klinefelter’s syndrome and chimerism. Furthermore, the cat is physically defective and cannot produce viable sperm.

Male calicos are rare because there aren’t many males born each year. The reason is simple: females produce only female kittens. Based on Bell, male calico cats are estimated to occur in fewer than 1 out of 1,000.

In order to predict whether or not a kitten will acquire the calico trait, sex chromosomes are crucial. Because their mothers have XX chromosomes, the majority of calico cats are female.

Males and females have one X chromosome at birth, while females have two at birth. This indicates that the ability to reproduce herself is ingrained in females genetically. On the other hand, males require an additional X chromosome to complete their genetic composition. They are therefore deficient in half of the genes required to produce progeny.

It is unlikely that any male kitten will develop into a calico cat in the future. This is so because the gene that causes the pattern of coloration can be turned off in females. But males never develop this ability.

Domestic cats rarely have calicos, and most breeders won’t even consider breeding them. There are some exceptions, though. For instance, occasionally, calico breeders will come across a male calico kitten. Additionally, a breeder may choose to retain a male calico rather than sell him if he does find one.

What Is a Calico Cat?

A Calico cat is a domestic cat recognized by its unique, tri-colored coat that usually combines shades of black, orange, and white. It’s important to note that Calico isn’t a specific breed but a color pattern that can appear across various cat breeds. Additionally, 99.9% of calico cats are female, with males extremely rare. Known for their vibrant and distinctively patterned coats, Calico cats are often cherished for their aesthetic appeal and are usually associated with a sweet and endearing temperament.

Genetic factors result in calico cats’ distinctive coloring. A combination of three colors characterizes it:

  • black (or blue in dilute calicos)
  • orange (or cream in dilute calicos)
  • white.

From one calico cat to the next, the distribution of these colors varies dramatically.

Breeds of Cats That Can Be Calico

Calico is a color pattern, not a breed of cat. However, this color pattern can be found in a wide variety of cat breeds. Here are some examples:

  • Scottish Fold: Scottish Folds, distinguished by their distinctively folded ears, can also be Calico
  • Siberian: This hardy breed can also be found in a variety of colors, including Calico.
  • American Shorthair: The colors and patterns of American Shorthair cats can vary, including calico.
  • Maine Coon: With their large size and long fur, these friendly, gregarious cats can also have a calico color pattern, which looks very striking.

  • Turkish Van and Turkish Angora: While it’s less common than other colors, these Turkish breeds may occasionally display calico coloring.
  • Persians are distinguished by their opulent long hair and round faces, but they can also be calico A Persian calico cat is quite a sight to behold.
  • Japanese Bobtail: Known for its bobbed tail, this breed is frequently depicted in calico color schemes and is widely represented in Japanese folklore and art. In Japan, a tricolored Japanese Bobtail is regarded as a lucky charm.
  • Manx: Cats with this characteristic lack of a tail can be found in a variety of colors, such as the three-color calico pattern.

Remember, whether a cat displays the calico pattern is genetics. The majority of calico cats are female because the cat requires two X chromosomes in order to have the black and orange colors in its coat.


Are calico males infertile?

Some cases of male infertility may be genetic in nature. This is the case in male calico and tortoiseshell cats because the combination of black and orange markings stems from possessing an additional X chromosome (these cats carry the chromosomes XXY instead of the normal XY that is seen in males).

Why is it rare to have a male calico cat?

Male calico cats are typically considered intersex or have a genetic abnormality. The calico coat pattern is linked to the presence of two X chromosomes (XX) in cats. Since male cats typically have one X and one Y chromosome (XY), they usually do not inherit the calico coat pattern.

Can you breed male calico cats?

A: I hate to burst your bubble, but although male calicos are rare, trying to breed one will be a bust. Approximately one out of every 3,000 calico cats is male, according to a study at the University of Missouri’s College of Veterinary Medicine, but they are generally sterile.

Can a calico cat have babies?

Yes, being calico (or tortoiseshell and white, as it’s called in non-US English) doesn’t affect a female cat’s ability to reproduce. Of course, it’s possible that she might be infertile for reasons unrelated to her coat colour.
