Tortoiseshell and Calico Color Patterns

Tortoiseshell and calico cats come in a great variety of the colors, including black, red, and white. Unlike what some people think, they're not different breeds. Their differences lie in their special color patterns. In this article I'll explain how the tortoiseshell pattern compares to calico. Both have the same colors (white, orange, and black) but the patterns are different. While a tortie coat might not include any white at all (like the cat on the above photo), calico coats always include white.

At home, we have one tortoiseshell cat (Chewy) and two calico cats, one with plain colored patches (Lilo) and one with tabby colored patches (Red). It was when I did my research for this article that I discovered that Red is a calico. She has quite a lot of white in her coat and her colored spots are not plain, but brindled. She is what's called a tabby calico.

In The Netherlands, we use only one word for these cats: lapjeskat. In English this means "patched cat."

Curiosity is the very basis of education and if you tell me that curiosity killed the cat, I say only the cat died nobly.

Why Tortoiseshell and Calico Patterns Are Different

Most tortoiseshell and calico cats are females. They have two X chromosomes, one for orange (XO), one for black (XB). They only pass one on to the next generation. Males, however, have one X chromosome and one Y chromosome, which is either orange (XO) or black (XB).

Here is more detail about how this works:

Female XO + Male XO = orange

Female XO + Male XB = mixed orange+black pattern

Female XB + Male XO = mixed orange+black pattern

Female XB + Male XB = black

Whenever a male tortoiseshell or calico cat is born, the father most likely had an extra X chromosome, XXO or XXB, which is a rarity.

Pigment Genes in Cats

Pigment genes are expressed in what we call melanocytes. When there is a mixed pattern, these genes surface to the skin and the colors mingle randomly, giving the cat that special brindled look. In tri-colored cats, there's a second gene interacting, which has no pigment at all. This results in either small or large white spots. This is why some cats look completely white but are not albino. Genetically, they have a brindle pattern, with a dominant white which won't let the orange and black surface to the skin.

  • The only difference between a tortoiseshell and a calico is the absence or presence of white spots. The calico pattern has an extra spotting gene, which produces white, unpigmented spots. Those white spots can be either small or very big. The spotting gene overrules the color gene, so you can have an almost white cat with a few colored patches, or a colored cat with a few white spots. Most of the time the colored patches are in the same color range as tortoiseshell cats: orange (red), black, and white.
  • Tortoiseshell cats (torties) 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. These cats often have a mottled or brindled coat. They can either be short haired or long haired and the color patterns can vary from very dark to very light.

My Calico Was a Stray Cat

One evening in 2002, I went into the barn and there she was: A cute, but skinny, teenage kitten with very big eyes. She was shy, but also hungry, and she ate until her belly was full. She may have come from a farm in the neighbourhood. They often have cats to keep the mice away. Or maybe she was just thrown out of some car. Who knows?

That's how Red came to live with us. It took a lot of begging and spoiling before she allowed me to pet her, but she never allowed me to pick her up and hold her in my arms.

When Red came into the house, we quite soon discovered that she must have had a difficult life before she ended up in our barn. She must have had some very bad experience with human encounters.

She comes to sit on your lap, purrs a lot, and actually loves to be petted, but when you pet her too much or you stroke her right to the end of her body, she suddenly will grab you with her claws. Her ears go back to her neck and she turns into a wild animal. You'd better get her off your lap by then. You can't pick her up, so the best way to do it is to stand up and she'll jump off. She has always been like that, all nine years long, so we keep her away from visitors.

What Is a Diluted Calico?

Dilute means less intensive. A dilute calico is a cat that has the same coloring pattern as a normal calico but the colors red and black are not so bright. It looks like they're a bit washed out so to speak. The black is greyish blue, the red is rather creamy as you can see in the photo below.

        Hi Gina Bobitt,

        What a great story to read about your cat. Good for you to take in a stray cat and care for her despite the fact that she's not friendly towards people. Sometimes I wish they could tell us their story and what happened to them. Only thing we can do is give them love.

        When you describe the story in the article about when you found your cat red the story is very similar to mine except there wasn't a barn and I took the cat in as a stray that was about 9 years ago to and when you were talking about petting her she has the same exact behavior and I keep her as a house cat and when I was living with my sister I kept her my cat in my room and she came out when the kids were not around she's not good with other people and she does strike out at him but I've had her for 9 years same as you it was good to hear your side of it because I know that there's other people out there going through some of the same things I am but she's my best friend and my convenient

        Hi EM, thanks for your comment. It's not so strange that your cats don't love each other as much as they did when they were young. Cats actually are loners, they don't really need the company of other cats to be a happy cat. They can also be quite territorial. As long as they don't fight all the time it's ok.

        I have 2 tabbico sisters. One is diluted the other is not. They loved each other until the age of 3. Now at age 5 they tolerate each other but don't act the loving way they did as kittens.

        Ha our tortie Amazon is almost exactly like how you describe Red, except she chooses teeth instead of claws for the most part. She also is a chronic "love nipper" when you pet her. She rarely goes into full out beast mode, but when too stimulated it's best to just leave her be. Silly felines!

        Doris_Mae, thanks for your story. Our cats have been strays most of the time and they all had/have their own background package to carry of which we'll never know the content. You just have to accept them the way they are and love them.

        My cat is an orange tabby, but she has a nasty attitude as well! She hates being picked up or pet too much, but her biggest issue is with other cats. As a stray, I believe she got attacked by other cats. She absolutely cannot be around other cats and will redirect her aggression towards me if she sees one. Okay, go back to your calicos and torties. I just wanted to share my story of my nasty kitty whom I love with my whole heart! :)

        # Rita: I don't think the way your cat holds her tail is breed related. Cats often hold their tail that way because they're excited in some way or other.

        I would dispute your use of the word "own" in the first poll question: how many of us actually own a cat? Do they not own us? Or at least decide to live with us! Currently we care for 17 cats, rescues of course, the latest one being the calico kittie rescued trapped in the house/garden behind us in the summer when she was a baby. We live in the south of Spain.

        Hi CrystalDragon3568. I'm so sorry I didn't see your post earlier. I haven't been around HP much due to busy busy times with my sheep. I'm glad you found my article useful. I think your cat would've been a Callico, but that's a guess. Without a photo it's not easy to say.

        Thank you so much for this! I was planning on making a Warriors fanfic with alot of tortoiseshells (they're so fun to draw, along with calicos!) and I thought that the only difference was that tortoiseshells have one main colour and two splotches of colours, whereas calicos are just tricoloured. This helped me learn alot, so thank you!!! I shall use this knowledge when creating semi-realistic cats, and if anyone asks me for a article on the difference between these two amazing colours of cats, then I will link them here! I also rated a 10/10, as this was so helpful!!! Thank you so much! Also, I have (had) two (now I have one) calico cats, and one of them (Tiger) ran away, but she was almost all black and orange with a tiny bit of white on her. We were told she was a calico. Is she a calico or a tortoiseshell? Reading this article made me think about that, so I thought I might ask. Thanks!

        Thank you for wonderful article (lens?) about calicos/torties, with beautiful personal pics and antidotes, and simplified genetics for myself!(-; I live in Kansas (KS) with Joey, a black cat with only 3 white hairs on his whole body (not sure what his coloration would be labeled based on your lens). My sister hand raised he and 4 siblings when feral mom birthed them under her deck in a thunderstorm and ran off never to return for them. Family members each took a "little one" at 8 wks., we had them neutered or spayed and I chose the little black fellow (who is now 16 pounds).

        I had just returned to KS in 2006 after living in Ohio for 20 yrs because my Multiple Sclerosis had worsened significantly and I needed family support. Where I now live are "independent living" 6-plex apartments. It is in the middle of the city and we are next to a medium sized cemetery. There were feral cats in the area that I began feeding 6 yrs ago with the gratious help of Michelle, my home health aide, who was an animal lover, though not so of cats (until she began developing personal relationships with some of the little guys... and Joey, of course). About 5 years ago with the great assistance of a wonderful feral feline organization that has a TNR program (Trap, Neuter and Retun) they helped stabilize the population and provide rabies shots for "the kids" who now number 9: Sylvester, Tommy, Arlo, Precious, Cleo, Little Yin, Mama, Blackie and Gabby. Six yrs ago a very petite "brownish" tortie(?) maybe 5 mo. old showed up on my tiny porch peering through the bedroom window looking at Joey. She did not seem to be befriended by my colony of cats but she and Joey quickly developed a relationship. Eventually I felt I needed? to bring her in for a number of reasons. I named her "Palette"and she's maybe 7 pounds. She has a huge attachment to Joey and having been feral has slowly developed a bond with me. Her nutrition was poor and she is "slow". She is very shy and needs the protection of Joey and me. I dearly love them both.

        I am glad to have found your web site and plan to share it with my friends of cats and feral cats. Thank you.

        I can never pass by any lens about cats! And yours was most informative and delightful!

        My Calico Paw Print (It is a polydactyl paw print):

        Two of my rescue cats have been long haired, polydactyl calicos. They came to me 30 some odd years apart but were both so identical in personality and appearance that I became convinced the second calico was a reincarnation of my first one. I had been catless for quite a while and my dad thought that I needed a kitten for my birthday. He did not know where to get me one. The wind blew a discarded newspaper his way and picking it up he found an ASPCA ad for kittens. I was so excited! But when I got there I wanted every cat and kitten I saw and started crying because I could not pick just one. Then I heard a cat calling and crying loudly from a distant room in the shelter. It sounded just like my Purrsia used to call me. I got my calico Purrsia when I was in the second grade. She was my best friend growing up. She lived to play with my daughter and died after a long life. I felt like somehow Purrsia was calling for me, some 30 years later. When I started through the door to find her, the attendant informed me that there were no cats available for adoption in that part of the shelter. I convinced them that this was my cat calling me. As she was making such a fuss crying and calling, they let me in to her cage. I could not believe my eyes when I saw her. She pressed her nose up to the cage and rubbed up against me and "talked" to me as if telling me all about all of her adventures during our separation. Marked exactly the same, with the same big polydactyl paws, chattering away to me in her same unique voice---I could not believe this was real. The shelter let me adopt her because it was obvious she was my cat. She had been their Mascot Shelter Cat and they were planning to keeping her. I had dreamed about Purrsia the previous night, and I did not know at the time that I was going to be surprised with a birthday kitten.

        This is a very informative article. I never heard of Calico cats before reading lenses about them. It seems to be an American term. In Australia multi-coloured cats are all tortoise shells. I have one now that is an absolute Gem and that is her name. Her last litter produced 2 beautiful ginger females and one of them is still here. She looks Red and her coat is unbelievably beautiful. Her daddy is a Turkish Angora and she has a wonderful personality. Being ginger and white she is not a tortoise shell but she is certainly unique and 'Red' certainly suites her as a name. Well done.

I once had a Calico cat who crawled into a crawl space in the laundry shed in the carport that was covered by the same roof as the house and found herself in the attic space. She proceeded to have 5 kittens up there which we discovered only by hearing tiny 'mews' in the ceiling of the living room! We only had a removable square in the hall ceiling to gain access to this small space above, so put up a ladder and sent our 11-year-old son up with a box and admonishes to make sure he brought back every single kitten (and mama cat). Success.

        I never knew how to tell the difference between Tortoiseshell and Calico cats. I've probably called each by the wrong name! Our vet told us that our cat was a "Diluted Calico." She is sweet. But her mom, a tabby, is much like your Red. A little bit wild.
