Differences Between Calico and Tortoiseshell Cats

Calico and tortoiseshell cats have an appearance that wins the hearts of all cat lovers. Although they are immediately distinguished from other cats by the unique color and pattern combinations of their fur and manage to attract attention, it is common for them to be confused with each other. You can find information about these cats, which are quite similar both in their fur colors and their somewhat grumpy personalities, and the differences between them in the rest of our article.

Characteristics of Calico Cats

Whether a cat is calico is determined not by its breed, but by the color of its fur. Almost all cat breeds have the potential to have calico fur. The most prominent feature of calico cats is that they have a tricolored coat that is 25-75% white, but also includes black and orange. Some calico cats have very light orange and black fur, and their black fur is even closer to gray.

Calico cats, regardless of breed, are known for their grumpy nature. However, calicos are devoted, loyal, and especially close to one person in the house. Most people find these cats interesting and energetic, but these characteristics can sometimes turn into neurotic behavior.

Calico Geni

You may have heard that calico cats are entirely female. However, although almost all calico cats are female, male cats with this coat pattern can rarely be found.

Calico fur is X-linked, and for this coat pattern to be visible, the cat must have two X chromosomes. Since males only have one X chromosome, it initially seems impossible for a male calico cat to exist. However, some male cats are born with an extra X chromosome instead of X and Y chromosomes, resulting in XXY chromosomes. This extra X chromosome makes it possible for male calico cats to be seen.

When the XXY chromosome is seen in humans, this condition is called Klinefelter Syndrome. All male calico cats suffer from Klinefelter Syndrome. While some cats show no symptoms, others may experience behavioral problems or obesity. Additionally, male calico cats have a higher risk of developing diabetes or heart disease.

Characteristics of Tortoiseshell Cats

Tortoiseshell cats, like calicos, can be found in almost every cat breed. However, tortoiseshell cats differ in appearance from calicos. Their fur is usually bicolored. The color pairs are black and brown, and tan and orange. In some cats, the black color may be characterized by slightly less pigmentation. In these cats, the black fur is more often seen as bluish-gray. Rarely, a very small area of ​​white can be found in the fur of tortoiseshell cats. Because the white color is in a very small area, the cat is not considered a full calico. These cats are usually called tortico.

Tortoiseshell cats are generally more aggressive than other cats. It is possible to see their moods change quickly. Although they can get angry quickly, they don't make much noise about what is happening around them and are calm for most of their lives. They are devoted to their owners and generally love to play. Thanks to these traits, they can get along well with other cats or children. It should also be remembered that the way these cats are raised has a great influence on their character.

Tortoiseshell Kedi Geni

Like calico cats, the tortoiseshell appearance is also an X chromosome-linked condition. Two X chromosomes are required for the tortoiseshell appearance. Basically, the genetic condition seen in tortoiseshell cats is the same as in calico cats. The majority of tortoiseshells are female, and males have Klinefelter Syndrome. Male tortoiseshell cats are naturally neutered and cannot reproduce. However, you should definitely consult a veterinarian to have these cats neutered. Because neutering eliminates the risk of testicular cancer and some behavioral disorders.
