7 Fascinating Facts About Tortoiseshell Cats
Are most tortoiseshell cats truly female? And where did the name tortoiseshell come from in the first place? Is ‘tortitude’ a real thing for tortie cats?
What could former president of the United States Ronald Reagan and actress Lea Michele possibly have in common? They both added stray tortoiseshell cats to their families! President Reagan kept his two tortoiseshell cats,Cleo and Sara, at his California vacation ranch. It’s reported that Michele found her tortoiseshell cat,Sheila, on a Paramount studio lot. That’s the power of the “tortie” — one of the nicknames for tortoiseshell cats. So, what exactly are tortoiseshell cats, and what’s so special about tortoiseshell cats? Let’s find out!
1. Tortoiseshell cats are not a breed of cat.
Tortoiseshell cats have a combination of two colors, usually black and red. There are variations of the black and red, too — black can be diluted variants of brown or grey and the red can be diluted to cream, gold or orange. Torties are called tortoiseshell because the coloring of their coats looks like tortoiseshell.
Tortoiseshell was a highly prized material used in manufacturing everything from jewelry to furniture until 1973. CITES (Convention on International Trade in Endangered Species) banned the use of real tortoiseshell worldwide at that time since turtle and tortoise populations were being decimated. Synthetic tortoiseshell is still popular. “What does that have to do with cats?” … you may be wondering. Well, the color combination is rarer than most coat cat colorings.
2. Tortoiseshell cats are predominantly female; it’s in the genes.
The chromosome linked to coloring in cats is the X chromosome. Females have two X chromosomes, carrying the orange and black codes. Males have a tiny percent chance of displaying orange coat color. And to further confound things, female cat heterozygous display a combination of orange and black, aka tortoiseshell.
3. Piebald is not a reference to a hairless dessert.
While tortoiseshell cats are two colors, if white is present, the cat is now considered piebald. But you probably know them as “calico cats.” Although, outside the United States, this term is not popular.
4. What about tortoiseshell cats and the much ballyhooed “tortitude?”
In an article on tortoiseshell cat personality, Maeve Conner gleans some insights from cat behavior expert and star of Animal Planet’s My Cat From Hell, Jackson Galaxy. “Galaxy says he has not found tortoiseshell cats to be feistier than average, but he does believe they tend to be ‘more sensitive to the stimulus around them.”
5. The tortitude heard around the world!
In 2016, articles touting tortitude spread faster than unchecked fleas in a cattery. Reputable publications such as the Sacramento Bee and the Seattle Times were sharing the results of a study released by University of California, Davis. The study, from a behavior expert at the highly respected UC Davis Veterinary Medical Teaching Hospital, was originally published in the Journal of Applied Animal Welfare Science. While the headlines were purporting “tortitude,” the reality is, “Researchers found no significant variations in aggression level associated with coat color at vets’ offices, despite common attitudes among veterinarians, technicians and shelter workers that some coat colors reflect cats with more peppery personalities.”
6. So, what are torbies?
Tortoiseshell coat coloring can mix it up in stunning ways when combined with tabby patterns. Yep, these types of tortoiseshell cats are called torbies.
