[Unchained] Weapon Attunement and Natural Weapons

[Helix7901]

When using the Automatic Bonus Progression rules, you get the ability to attune yourself to one or multiple weapons, giving them an enhancement bonus.
My question is, can a character Attune himself to a natural weapon, like a Claw or his Bite natural weapon?
If yes, a character with 2 Claws have to attune himself separately to his 2 claws, using the rules for 2 weapons, or does he count them as a single Natural Weapon?

Thanks for the help guys...

A natural weapon is still a weapon, so I would think you can attune it.
That said, Claws are generally treated as two weapons, so if you can only attune 1 weapon, I would think you can only attune 1 Claw.

The pricing of Amulet of Mighty Fists is roughly 2x the price of an enchanted manufactured weapon. This means that a creature trying to enchant multiple natural weapons will go through roughly the same gold expenditure as a creature trying to enchant two manufactured weapons for the purpose of two-weapon fighting. Therefore, I suggest one workaround: When you can attune two weapons, you can instead attune all your natural weapons.
The above workaround doesn't really work when the weapon attune bonus is uneven, such as at level 17 (+4/+3). That said, the unchained book is about houserules anyway, so I recommend you make your own houserule to handle that case.
I personally would handle it as, you choose one natural weapon to get a +4 bonus, and all other natural weapons get a +3 bonus.

Sorry I'm late to reply, but thanks for the feedback anyway!!

I would probably treat a set of claws as a single weapon, as they are often treated as a pair. As an example, the evolution for an eidolon to gain claws, it isn't per claw, it's per pair. In fact, I can't recall ever seeing something with a single claw attack (except for a claw bearer using a one handed weapon)
