Fun facts about the Siamese

  • All Siamese kittens enter the world solid white, developing point colors on their extremities only after birth. [S2][S27]
  • The coat works as a living thermal map, growing lighter during hot seasons and darker during cold weather. [S25][S27][S41]
  • Shaved areas of skin from clinical visits often regrow darker fur initially because cooler exposed skin activates pigment enzymes. [S27]
  • United States First Lady Lucy Hayes received a Siamese cat named Siam at the White House in 1878. [S2][S7]
  • The Siamese contributed genetic foundations to multiple modern breeds, including the Oriental Shorthair, Balinese, and Tonkinese. [S1][S7][S42]
