Eidolon natural attack questions

[Cuteshark]

I'm joining a game as a 6th level summoner, and from what I understand, this gives my eidolon up to four natural attacks, but I have a couple questions.

1. If claws is my only attack, would I still get the 1 and 1/2 str mod bonus to my damage, or no since it's technically 2 attacks? Is an attack with both claws a full round action?

2. How many primary natural attacks can I make in a full round of combat, and with what dmg bonuses, does this number increase if I select more than one natural attack? if I move or perform a minor action?

1. The 1.5 mod applies only if you have a single natural attack i.e. a bite attack. Claws allows for 2 attacks.

2. You can make 1 natural attack per limb capable of making a natural attack. This requires a full attack action if making more than 1 attack.

3. Standard rules for the full attack action apply: you can still 5' step, take a swift action and take free actions. You cannot take a move action.
