People sometimes call the average domestic cat a tabby, but tabby is not a cat breed — it is actually the pattern of kitty’s coat. And it happens to be the most common of all the feline coat patterns. Technically speaking, no matter what colors or markings you see on your cat, all felines possess the tabby cat gene. Other cat colors or patterns may hide those tabby markings, but they’re always present.

First, some tabby basics:

Sometimes you can see those faint tabby markings on a solid-colored cat who is sitting in the bright sun. And have you ever seen a solid red or orange or cream cat without the familiar tabby markings? You won’t, because the gene that makes a cat red or cream also makes the tabby markings visible.

All tabbies have thin pencil lines on their faces, expressive markings around the eyes, and a distinct letter “M” on their foreheads. Some believe the “M” is for Mau, the word for “cat” in ancient Egypt. Others think the “M” stands for Mohammed, who loved tabbies. Still others believe it is the blessing of the Virgin Mary.

There are five types of tabby coat patterns, each possessing its own unique markings. We’ve listed them below alongside photos of each.

See if you can figure out which tabby your cat is:

The 5 Types of Tabby Cat Patterns

1. Classic Tabby Cat

The classic tabby has bold, swirling patterns along his sides — much like a marble cake.

This tabby is called a “blotched tabby” in some regions. The pattern of circular smudges on the classic tabby’s body closely resembles a bullseye.

2. Mackerel Tabby Cat

A mackerel tabby has narrow stripes that run in parallel down her sides. This is what some people refer to as a “tiger cat.” The body has narrow stripes running down the sides in a vertical pattern.

Ideally, the stripes are non-broken lines; evenly spaced. They branch out from one stripe that runs along the top of the cat’s back down the spine, resembling fish skeleton — which is why the term “mackerel” is used to describe it.

3. Spotted Tabby Cat

A spotted tabby has spots all over his sides. These spots can be large or small, and sometimes appear to be broken mackerel stripes. They can be round, oval, or rosettes.

Often, a mackerel tabby with a broken pattern resembles a spotted tabby. It is not known whether these spots developed from a mackerel tabby or come from a separate gene.

4. Ticked Tabby Cat

A ticked tabby cat (sometimes called Abyssinian tabby or agouti tabby) does not have the traditional stripes or spots on her body, and may not, at first, seem to be a tabby. However, like all tabbies, this coat pattern has tabby markings on the face and agouti hairs on the body.

What are agouti hairs? If you look up close at the lighter parts of a tabby’s coat, you will see that the individual hairs are striped with alternating light and dark bands, known as the agouti hairs. The ticked pattern is displayed prominently in Abyssinians but also appears in mixed breeds.

5. Patched Tabby Cat

This is the term used to describe a tortoiseshell (also called tortie) tabby. In the typical form, there are separate patches of brown tabby and red tabby on the same animal.

A tortie who also carries the tabby gene is often called a torbie. Patched tabbies can show any one of the above four distinct tabby patterns. The markings are usually more apparent on the legs and head.
