Tabby cats have a distinctive feature, their M mark on their foreheads. Different legends try to explain this particular mark.
One legend relates the M to the word mau, which in ancient Egypt meant cat.
Another story tells that a tabby cat came to comfort baby Jesus, and in gratitude, the Virgin Mary stroked his head and left that mark on him. There is also an Islamic legend about Muzza, a cat who saved his master Mohammed from a poisonous snake. That is why all tabby cats were rewarded with that M on their foreheads.
