How to make creature summons not aggro NPCs

[Skurei]

I'm trying to make summon spells, like the toy soldiers, that will just act like familiars, following my character and fighting my enemies, but won't attack random NPCs or chickens all the time.

 

For my first spell I'm made it to where it'll spawn 5 tiny saber cats, but I can't figure out how to make them not attack everything. I've added the faction WEPlayerfriend, so they don't attack me, is there a faction to where they'll only attack my enemies? I tried it before a long time ago, but I think I remember that no matter what I tried they always attacked NPCs.

Try removing your Sabrecats from the predator faction, and change their aggression to neutral.
