Beastmorph natural attack stacking

[Cryov]

If I use my feral mutagen and get my 2 claws and bite then with the beastmorph archtype choose a cat to beast shape into, do I get 2 more claws and a bit?
How does it work?

Lets assume this is the beast shape 1 or 2 spell, not alter self.

You don't get natural attacks with Beastmorph archetype. You only gain a monstrous appearance, and choose one ability for the list in the spell (darkvision 60 feet, low-light vision, scent, and swim 30 feet).

You don't actually change into something else.

Beast Shape = Polymorph effect
"In addition to these benefits, you gain any of the natural attacks of the base creature, including proficiency in those attacks. These attacks are based on your base attack bonus, modified by your Strength or Dexterity as appropriate, and use your Strength modifier for determining damage bonuses."
Straight from polymorph rules.

Is the Beatmorph Mutagen defined as a polymorph effect?

Thanks for the responses, had a friend point out what was wrong.
The Beastform Mutagen just lets me choose powers from the beast shape ability, not assume the shape.

You mean it was exactly what Samasboy1 said but you argued with?
