Now, we all know that if a person yawns (or even talks about yawning), then there's a good chance that any nearby people will also yawn. And contagious yawning in animals happens all the time as well, as a kind of warning signal or something. What I'm interested in is cross-specis contagious yawning. Has anyone ever, for example, yawned in front of their pet dog, and had their dog yawn in response? I'm just curious. ^_^
