Calico Cats – Tricolor Beauties

It is not difficult to identify a calico cat. Their three distinct hues stand out against the background of their vibrant coat. There is a school of thought that holds that calico is a breed of cat. Some people believe that it is a colour. Calico, on the other hand, is a specific type of multicoloured pattern. A calico that has not been diluted at all is predominately white and features distinct spots of orange (or red) and black. There are a few chocolate-colored cats, but chocolate-colored cats are quite uncommon.

By contrast, a diluted calico will have a coat of white, cream, blue (sort of like a bluish gray) or cinnamon. The washed out colors are caused by the dilution gene.

But what causes this unique pattern? It’s all about genetics. More specifically, the answer lies in the chromosome X, which contains the code responsible for fur coloring in cats. The Y chromosome, by contrast, contains no information associated with color. Now, a set of two X chromosomes are required to produce a calico. Male cats have a set of XY while female cats have a set of XX, so most calicos happen to be female. Though rare, you will find male calicos, which for the most part happen to be sterile.

Interestingly, many people confuse calicos with tortoiseshell cats. At first glance, they may look similar, but upon closer examination they’re quite different. The main difference being that tortoiseshell cats have very little or no white fur. Some people confuse the two because some tortoiseshells display more white hair than usual, but this hair is mostly mixed in with the other colors. By the way, the two other colors are also blended. Calicos, on the other hand, have three distinct patches of color, white being the most prominent.

Another interesting fact is that not all tricolor cats are calico cats, some cat breeds like the Himalayan and Javanase have coats with tricolor points but these are not considered to be true calicos.
