A tortoiseshell cat is a cat with a coat coloring named for its similarity to tortoiseshell pattern. The coat is bi-colored and looks like the shell of a tortoise, with colors that are either "bridled" or "patched". Tortoiseshell cats are almost exclusively female, and male tortoiseshells are rare and usually sterile. Although tortoiseshell cats are not a specific breed, several breeds can exhibit tortoiseshell markings, such as American shorthair, British shorthair, Cornish Rex, Persian, and Maine Coons. Tortoiseshell cats are known for their unique personalities, and their owners frequently believe their cats have increased attitude, affectionately described as "tortitude". However, there is little existing scientific evidence on the matter. Here are some additional facts about tortoiseshell cats:

• Tortoiseshell cats are beautiful creatures affectionately called “torties” .
• Their endless amount of energy can at times come across as being headstrong or simply being a bit more sensitive than other cats, making it all the more important to provide sufficient playtime.
• Tortoiseshell cats are not a breed, but the name is used to describe their coat color and pattern.
• A tortie’s color palette can either be patched or brindled, which is when the colors are mixed together. There are also tortoiseshell cats with tabby stripes, known as “torbies” .
• The life expectancy of a tortie cat will vary depending on the breed and overall health.
