Feral Mutagen Alchemist looking for more natural attacks.

[RUMBLETiGER]

I'm playing a Vivisectionist, Beastmorph, Alchemist Gnome making the most of the Feral Mutagen. Essentially I Bite/Claw/Claw with sneak attack progression, little ball of angry fury. Fun times.

My question is, are there any reasonable methods to acquiring additional natural attacks that could help me? A level dip or two in another class is reasonable, I'm open to ideas.

I'm coming from 3.5, fairly new to Pathfinder, don't know the ins and outs very well.

Thanks.
