What it does
Checks if your Hunter pet's mood is the one you choose: Unhappy, Content or Happy.
Why you might use it
Keep a Hunter pet fed and useful: remind yourself to cast Feed Pet when it is not Happy, or hold off on a pet-damage cooldown while it is Unhappy. No pet, or a pet that is not a Hunter pet, is in none of these moods. Classic Era, Burning Crusade and Wrath of the Lich King only. See also Have Pet.
Example
your pet is Unhappy
