How the tabby cats got the "M" on their forhead
When Jesus was born, and lying in the manger, they say that a small cat with stripes joined the people present while they fawned over the baby. They say that this particular cat was very curious – and decided to have a better look – pressing his head upon the crib. When he drew his head back – stripes on his forehead appeared – forming the letter “M” for “Manger” as a reward for his curiosity.
Note: Not sure if that’s how all the stories go – but I’ve heard it once and thought it was very cute.
