Treats!  Hey, it works with this bunch.

Take special note at the top plate that Kako on the left has no problem eating from the same dish as Vazra on the right, and this despite them being sworn enemies.

At the bottom plate, left to right is Grendel, Kazon, and Loki, all of whom get along just fine with each other while they all have some “issues” dealing with Kako.

Don’t we all…

But if treats work in this household, there’s no reason we shouldn’t give it a try elsewhere.
