This can get a little confusing, but the results are worth the struggle!Īll of a cats physical characteristics are determined by their genes, which are arranged in 19 pairs. How does this happen?īefore we get into the reasons for dilution, it helps to understand the genetics behind the standard tortoiseshell coloring. Standard torties have a mix of orange and black fur, either finely interspersed (a brindle tortie), in big splodges (a patchwork tortie), or somewhere in between (just a tortoiseshell tortie!) Dilute tortie cats have a tortoiseshell coat pattern with one remarkable difference: instead of the striking, dark mix of orange and black, dilute tortoiseshell cats have a muted, almost blue and yellow color. Tortoiseshell cats attract attention wherever they go. In the world of cat fanciers, some coat colors elicit more curiosity than others. So, is our post clear? If you have any questions, feel free to leave them below.Tortie is short for “tortoiseshell”, a popular coat pattern seen on many cat breeds. On the other hand, Torbie cats also contain many interesting facts about their creature that make you amazed. Nevertheless, the way to distinguish them is quite easy you just need to pay attention to their coat, then the answer will be revealed. Some people have mistaken that they are one. Torbie cats are exquisite creatures which have some similarities to Tortie cats. In this case, you might consider buying a tall baby gate for cats to keep them in place. Besides, Torbie cats can be quite dangerous to young children and baby, especially the young cats. If you are holding an intention of owning a Torbie, consider carefully because your house’s stuff may not be intact. Unlike normal cats, a Torbie cat loves running, jumping, and scratching around the house. The name Tortoiseshell not only concerns to the coat but also about their personality. In contrast, their colors have been recognized as the breed standard by some pedigree breeds. That’s why many people think Tortie is non-standard breed. However, tricolor is just a common name for cats which have specific features of the coat. We all know that Torbie cats belong to the tricolor breed. That’s why female cats always have orange on their coats, they hold OO, which becomes their dominant genes. About color gene, orange is denoted as O, non-orange is denoted as o. It sounds interesting! But why? That’s because when female eggs combine with male sperms, they will produce XX (female cats) and XY (male cats). According to a research, there is only 1 male among 3000 Tortie female cats. If you notice, most Torbie, Tortie and even Calico cats are female. Besides, the funny fact is that without orange, they are neither called Tortie, Torbie nor calico. That’s why all of them have orange on the fur. Both dominant genes and recessive genes of both Torbie, Tortie, and Calico contain orange. The key to explain this is deep inside their gene. You may recognize orange always presents on your Torbie’s coat, even just a little. Besides, the coat on the back has many patches which stick to each other. In particular, they are more white than others. This breed is a little bit different in the color and shape of the pattern on their coat. Torbie cats have a “brother” called Calico. ![]()
