Coalition, intrigue, ambush, destruction and pride: Herding cats can be challenging

Herding cats can lead to coalition (of cheetahs), intrigue (of kittens), ambush (of tigers), destruction (of wild cats) or pride (of lions). In this tutorial, I will present the cat language to write consistency models as a set of constraints on the executions of concurrent programs. A cat model can be executed within the herd tool [3], which I will use during the tutorial.
