Kitty yawning
Have you ever watched a cat yawn? His mouth opens so wide, you can count every tooth. It has been estimated that a cat yawns on the average of 109,500 times in his life. Lots of animals yawn. Humans yawn; the earliest yawn often occurs 11 weeks after conception – that’s before the baby is born. The yawn becomes contagious somewhere in the first five years of life. Chimpanzees and apes yawn, and they yawn infectiously just like us. Fish and birds also yawn. ~Virginia Wells, PetPlace
