Hey Pet Parents & Pet Lovers,
After we adopted Kalista a number of our friends congratulated us on our beautiful new Tortoiseshell Cat. The only issue was… Kalista is not a tortoiseshell! It can be pretty hard to pin down what breed of cat you have, and although Tortoishell isn’t a breed, it can still sometimes be confusing what cats with this colouring are called.
What Defines a Tortoiseshell Cat?
Tortoiseshell cats or Torties are commonly a mixture of black and orange. Torties don’t always have dominant colouring and can be born with something called “dilute colouring” which simply means that the black and orange appear lighter on their fur.
What Defines a Calico Cat?
While Calicos share a similar colouring, being black and orange, they also have patches of white fur on them. This makes our cat Kalista a Calico.
So Why Do Some Cats Have White Fur And Others Don’t?
Well, it comes down to genetics. The colours black and orange are carried in the X chromosomes, while the colour white is expressed from your cat’s genes. These genes are called melanocytes and have a simple “on-off” function. While any cat can have white colouring, not ever cat can express both orange and black. (If you’re interested in why check out my post about it here.)
Do All Calicos Have Big White Spots?
Nope! Some Calicos only express very, very little white on them. This can be as small as a cm spot on your cat’s body. Even though the spot may be extremely small, doesn’t make your cat any less of a Calico!
Are Calicos or Torties Always Short Hair?
Nope! Calicos and Tortoiseshell cats can be almost any breed, including long haired! There are, however, some breeds that express these colourings more frequently than others.
Do Calicos and Torties Share a Similar Personality?
Although not completely scientifically based, it is believed that both Torties and Calicos have a very particular personality. Being a Calico owner, I can confirm that my cat shows signs of “Tortitude” or “Calico Attitude.” If you think that your cat has a particular attitude, you should definitely check out this article for a description of both.
Are There Any Other Names for These Cats?
Yes! Calicos are also called tri-colour cats or tortoiseshell with white. Torties, unfortunately, don’t have any other names/nicknames.
Interesting read!
I knew they were not the same, but now you have explained why.
Even us meezers have different points as they are known. (And a tendency to crossed eyes…)I am the usual sealpoint, but there have been blues here and chocolate too. There are many more as well. Flame points and lynx points are the most striking in petcretary’s mind. Minko was blue, but he had visible tabby stripes on his tail if the light was right…a dis-qualifier if he had been a show kitty…but to us here, he was purrfect! Except for the biting of cords trait and his illness of course…sigh…we still miss him…even after about 18months…
I couldn’t imagine ever getting over the loss of a furry friend. Even though she was mini, we still miss our angel Twitch. Losing her really made me realize how much pets do mean to us, even after they’re gone.
I always wondered this after seeing someone claim they are the same. Cat genetics are so confusing – especially when you include coat pattern in addition to breed.
I feel like way too many people have the impression that they are the same, which is a big reason why I wrote about it. I agree though, cat genetics are confusing! I couldn’t tell you what either of my cats are other than “domestic short hairs” or… “maybe tabbies” haha!
