Is this the most adorable example of teamwork ever?
Clearly, birds like dogs way better than they do cats, and we can see why. If we learned anything from Looney Tunes, other than umbrellas do nothing to protect you from falling rocks, it's that cats and birds don't mix. And that simple truth is playing itself out in viral videos. Remember the bird annoying the sleeping cat? Clearly, that was retaliation for generations of species warfare.
But birds and dogs are a whole other thing. It just goes to show, the enemy of your enemy doesn't have to be your enemy.
