Why all cats have the letter M on their foreheads?

It's a fun observation, but there's no scientific basis for the idea that all cats have an "M" on their foreheads.

While the marking on many cats might resemble the letter M, it's actually just a natural pattern of fur coloration.

The markings on a cat's forehead are part of their unique genetic makeup, and the pattern can vary widely from cat to cat. Some cats have a very distinct "M," others have a less defined mark, and others have no markings at all on their foreheads.

The belief that all cats have an "M" is a common misconception that has been around for a long time. It's likely that people have noticed the resemblance to the letter M and started to believe it was a universal feature.
