According to VCA Hospitals, the feline version of these diseases cannot be transmitted to people as the biochemistry involved has too many variables for any cat to pose as a threat to people.

Feline leukemia and feline AIDS are two diseases that spread through bites of infected cats upon other cats. There are also a number of other health-related issues when cats, including calicos, mate. Furthermore, with an already disheartening amount of unwanted cats as it is, adding to the problem is just as inhumane as animal abuse. Spaying also reduces the threat of mammary cancer as well. With the ovaries removed, the hormones that encourage cancerous tumor growth are greatly reduced. Spaying a cat before her estrous cycle greatly reduces the risk of cervical cancer, as well as eliminates the risk of ovarian cancer. Furthermore, since the vast majority of calico cats are female, there is the issue of birth control.

Just like people, each cat, including calicos, will have their own genetic makeup that will play its role in a cat’s immune system, plus other health considerations. However, since calico cats are found within a wide variety of breeds, taking their ancestry into consideration, plus their lifestyle, play deciding factors in a cat’s overall health. Caring for Calico CatsĬalico cats are not a special breed of cat, but they are almost always female. Although not life-threatening when this exception happens to a male cat, this is considered a birth defect and as a result, is not favored as a suitable breeding option. While there are always genetic exceptions, such cases are extremely rare and are always connected to some type of medical issue. This, according to science, suggests the reason why calico cats are always female is due to the locus of the gene that causes color inhibition, the white emerges along with patches of two other colors, which are usually orange and black. Also referred to as Barr bodie, genetic scientist, Mary Lyon, proposed in 1961 a concept known as X-inactivation, which meant one of the two X chromosomes found in female cats seems to shut off, which then results in the coat color patterns similar to mice. In 1959, it was learned by Japanese biologist, Susumu Ohno, the dark masses were X-chromosomes. This did not exist among any of the male cats that were studied. Murray Barr took it upon himself to study calicos in 1948 when it was observed each of them sported dark drumstick-shaped masses located inside the nuclei of the nerve cells belonging to female cats. While the calico cats are not a specified breed of cat, the following breeds that allow calico coloration as formal standards in shows are The only difference between the two is the colors and patterns featured on their coat. However, calico cats are indeed tortoiseshell cats in every way. As is the case with male calico cats, it is extremely rare to find white on a tortoiseshell cat. Tortie cats normally have their fur mottled that is either black-orange or grey with cream. Sometimes, the calico cats are confused with the tortoiseshell (tortie) cats.

In this case, it’s a condition called Klinefelter Syndrome, which means the male cat will also face issues of sterility. Only in rare circumstances will a male cat sport a second X gene. Because male cats only have a single X chromosome, the majority of the time they’re either just one color or two. This is commonly found among female cats as their genetics feature a maternal X chromosome and a paternal X chromosome. This is because the genetic determination of coat colors involved is directly linked to the X chromosome. It is extremely rare to find a male calico cat, but it has been known to happen from time to time. In some cases, even grey can appear in the coloration of this domestic breed of animal Normally, calico cats will be of the female gender.

Calico cats are members of the feline species that can have anywhere from 25% to 75% white fur that features large patches of black and orange in a tri-colored format.
