Looking to verify rules interactions.
Weapon Finesse explicitly states natural weapons count as light weapons.
The Faq states you can use dexterity instead of strength on disarm, sunder and trip maneuvers while using a finesse weapon.
A creature with the Trip ability gains a free trip attempt when scoring a successful hit with the appropriate natural weapon.
With the above rules, I would assume trip attacks made as a result of a successful natural weapon attack would use dexterity instead of strength. Monster stat blocks that I have looked at (e.g. cheetah have weapon finesse but do not have a CMB listed for trip attacks using dexterity.
