Why do some Maine Coons have an M on their forehead?

Many Maine Coons have an M on their forehead and this can only signify one thing: they are tabbies! Tabby is the most popular cat pattern and the forehead M is a dominant tabby trait.

Tabby cats can be purebred or mixed breeds and their forehead Ms can be prominent or barely visible and really vary in appearance.

Do all Maine Coons have an M on their forehead?

Not all Maine Coon cats have an “M” shape on their forehead because it’s a characteristic only associated with tabby cats. This means non-tabby Maine Coons do not exhibit this marking.

The “M” shape is formed from darker hairs in the middle of a tabby cat’s forehead, just above its eyes, and is more prominent in some cats than others.

Mackerel (Striped) Tabby

Why do tabby cats have an M on their forehead?

The forehead M is a distinctive feature that has intrigued cat lovers for generations. While its exact origin remains a subject for debate, there are several reasons why some cats have this marking:

Genetics

The “M” marking is inherited genetically and is more commonly seen in tabby coat patterns. It is caused by the distribution of pigment-producing cells in the fur, resulting in darker hairs forming the shape of an “M” on the forehead.

Evolution

One theory suggests that the “M” marking may have evolved to provide camouflage and protection for wild cats in their natural habitats. The darker pigmentation on the forehead could have helped break up the outline of the cat’s head, making it less visible to predators or prey.

Functional Purpose

Some researchers speculate that the “M” marking may serve a functional purpose related to a cat’s vision or sensory perception. It has been suggested that the darker pigment on the forehead could help reduce glare or enhance visual contrast in bright light conditions.
