Improved Grab on AoO

[jiriku]

Can a character use improved grab and rake when attacking as a standard action, or making an attack of opportunity?

Scenario: A druid PC is polymorphed into dire tiger form. An enemy moves away from him. The druid uses his bite as an attack of opportunity, hits, initiates a grapple, and follows up with two rakes. His opponent took three hits and is now grappled. That's one heck of an opportunity attack! Legit?

No, he can only use rake attacks when he charges + pounces, or takes a full attack action. The note about using them in a grapple is there because otherwise you're normally limited to attacking with one weapon (a bite or claw usually) when grappling regardless of how many you have.

To clarify: You are limited to attacking with one natural weapon.

Creatures with a good BAB can round out their attacks with unarmed strike attacks, grapple checks to deal damage, or other legal grapple maneuvers.
