Scientists are still on the track of why humans yawn, and to add further interest, there are now many studies on which animals yawn and why they do so. If you’ve ever owned a fish, a reptile, a cat or a dog, or even a rat, you may have noticed these animals yawn. In fact most animals yawn, but it’s probably not because they’re bored or sleepy.
