I wonder if there is any animal that doesn't yawn.
From the pets that I own, I knows these animals yawn:

Dogs
Cats
Birds
Fish
Turtles
Hamsters

I also saw wild monkeys yawn frequently in the park.

I always suspected the guy next doors to be another species. If I think back, dont remember seeing him yawn as well !!
