Hunter - Cataclysm Pet/Stable Interface
The Call Stabled Pet has been revamped in Cataclysm.
You can now have 5 active pets and 20 inactive pets.
You can swap between your active pets at any time without any cooldown. The only restriction is to be out of combat.
To change your active/inactive pets, you have to visit a Stable Master in the nearest town.

Sadly, the feature is currently heavily bugged on beta realms and you will have to wait the next build to give it a try.
