Cats come in many beautiful and unique colors and patterns, some more common than others. “Torbie” refers to a tabby tortoiseshell color pattern.

A torbie cat displays patches of the tortoiseshell pattern and the tabby pattern. Not only is torbie one of the rarest color patterns seen in cats, some people say that torbie cats have unique personalities.

Torbie cats aren’t hugely common, and the unique nature of their coat pattern adds to their air of mystery. But do they have any other special traits?  Read on for some interesting facts about torbie cats, including how to tell the difference between torbie, tortoiseshell, calico, and tabby cats.

1. A Torbie Cat Is Not a Specific Breed

The term “torbie” refers to a pattern, not a breed. This interesting coat type can appear in many breeds and mixed breeds. Any breed that comes in the tabby or tortoiseshell patterns can also come in the torbie pattern.

2. Torbie Cats Are Almost Always Female

Almost all tortoiseshell cats are female, which means almost all torbie cats are also female. For a cat to have the tortoiseshell pattern, they must have two X chromosomes (XX), each carrying the alleles needed to create the tortoiseshell color pattern. Two XX chromosomes always make a cat female (males have one X and one Y chromosome), so the tortoiseshell pattern is usually only seen in female cats.

In very rare cases, tortoiseshell or torbie kittens are male. 

3. Torbie Cats Are Quite Rare

Tortoiseshell cats are somewhat rare, but torbies are even rarer. The patched tabby pattern is less common than some other tabby patterns like classic or mackerel. The unique coat pattern of the torbie is technically patched tabby mixed with the tortoiseshell pattern, and the combination of these two patterns makes the torbie a rare sight.

4. Torbie Cats Have Sassy Attitudes

Like tortoiseshell cats, torbie cats have a reputation for being feisty feline divas. In tortoiseshell, this tendency even has a name: tortitude. Since torbies are part tortoiseshell, it makes sense that some torbies display a similar temperament. Whether tortitude and “torbitude” is a real behavior phenomenon or simply a fancy of the human mind is up for debate, but some research has shown associations between a cat’s temperament and their color—let’s call it the “tortitude theory.”

5. No Two Torbie Cat Patterns Are Identical

Torbie cats are special because their fur mixes the stripes of tabby cats with the fiery patches of tortoiseshell cats, creating a unique blend of colors that’s hard to find elsewhere. While tabby and tortoiseshell patterns are beautiful on their own, they become even more striking when they come together in torbie cats, and each individual torbie has a slightly different pattern.
