This has been the source of a lot of argument in my group so I wanted to post a question that answered it once and for all. I can see both sides of the argument, but I was wondering who was correct.
----------------------------------------------------------------
Multiattack
An animal companion gains Multiattack as a bonus feat if it has three or more natural attacks and does not already have that feat. If it does not have the requisite three or more natural attacks, the animal companion instead gains a second attack with its primary natural weapon, albeit at a –5 penalty.
---------------------------------------------------------------
Through levels and progression an animal companion would gain this feat at level 9.
Assuming that you are level 1 and have an animal companion with 3 natural attacks does the animal companion automatically gain this as a bonus feat before level 9?
Or
If the animal companion has 3 natural attacks and reaches level 9 does he gain Multiattack as a bonus feat at level 9?
Animals with 3 attacks do not automaticaly get this feat. Animal Companions of (an effective) Level 9 Druid get this feat, as per the Animal Companion table.
