Cat Form is a shapeshift druid ability learned at level 8. Similar to a Rogue, it relies on an energy bar and combo points to use most of its skills. Druids in Cat Form also gain the ability to Track Humanoids, making a cloaked Cat Form druid perfect for PvP ambushes.
Cat Form uses Energy instead of Mana and can stealth, like a Rogue.
Blizzard has redesigned the Cat and Bear forms, which were released with Patch 3.2.0. There are now 5 different fur colors, designated by your hair color.
Tips and tactics
A druid in Cat Form can use both stealth and Track Humanoids to ambush people in PvP. By default, if you have no profession tracking on, when you shift into Cat Form, Track Humanoids is automatically activated once you have learned it.
