Extremely important news update from Assassin's Creed: Origins. You can pet kitty cats.

A few times while loitering in small towns, I noticed that the local cats would eventually wander over to take a look at me. First one would arrive, then maybe a couple more, depending on how long I waited. The cats will sit at your feet, wind around your legs, and even follow you around the town, provided you don't run too fast or too far. And, there's a way to pet them.
