![]() They present as male cats but can have tortoiseshell coats because they have two X chromosomes. According to ASPCA Pet Insurance, very rarely, males are born with XXY chromosomes. Males, on the other hand, have XY chromosomes, so their coats can either be black or orange. Females, who have XX chromosomes, can display both black and orange colors in their coats. One carries the gene for black fur and the other form codes for orange fur. The female chromosome X has two versions. The bad news is that one health issue can occur because your cat is a tortoiseshell, but it’s rare. Torties can have long or short hair, depending on their breed. The tortoiseshell type occurs in multiple breeds like the Persian, Maine coon, British shorthair, American shorthair, and Cornish rex. Good Housekeeping explains that torties have multicolor fur of black, reds, and oranges. They have a bunch of interesting info on them in general.The good news? Almost no health issues come with your cat being a tortoiseshell, and that’s because tortoiseshell is a color, not a breed. It's a page that register male calicos/torties, and even some that were know to be fertile. If you are still curious and want to know more I definitely suggest you check out this. Hope that cleared things about male calicos and tortoiseshells up a bit. They however about 90% of the time can't have kittens. ![]() They are not impossible to have, they are not all still born and the mother does hate them for any reason. there is noting different about male calicos and tortoiseshells, beside their color that makes them different from if they were born a different color, beside one thing and I will get to that. Calico and tortoiseshell is just a color pattern the only reason they are rare is because if the genetics that form the color pattern don't form in male cats that often because like explained above when a male calico or tortoiseshell is born it likely means the father had to X in his genetics which only effects color. There are lots of stereotypes about them that aren't true. I have heard a lot of things that aren't true about male calicos and tortoiseshells so I'm going to try and explain them. ![]() Whenever a male tortoiseshell or calico cat is born, the father likely had an extra X chromosome, XXO or XXB, which is a rarity. Here is more detail about how this works:įemale XO + Male XB = mixed orange+black patternįemale XB + Male XO = mixed orange+black pattern Males, however, have one X chromosome and one Y chromosome, which is either orange (XO) or black (XB). They only pass one on to the next generation. They have two X chromosomes, one for orange (XO), one for black (XB). Most tortoiseshell and calico cats are females. They can either be short haired or long haired and the color patterns can vary from very dark to very light. These cats often have a mottled or brindled coat. Tortoiseshell cats very often have only two colors, red and black, with no white at all, but color include black, orange (red), brown, black, cream, cinnamon, and blue. While a tortie coat might not include any white at all, calico coats always include white. Both have the same colors (white, orange, and black) but the patterns are different. Their differences lie in their special color patterns. The two colors along with the white are most commonly orange and black, but can come in a great variety of the different shades of the three main colors. Other times there is very little white, almost to the point where you don’t know it’s there, and that’s a tortoiseshell (or commonly known as tortie). Sometimes there is a lot of white, which is referred to as a Calico. Tricolor refers to a coat color that is the combination of 2 colors plus white. No, like tabbys they are only a color pattern that is found in many breeds. Calicos, tortoiseshells, and torbies all belong to a category of cat colors called tricolor. Let's start off by talking about what calicos and tortoiseshells are. ![]()
