This article has been updated for Kenshi version 0.99.1 (Experimental).
Fauna are organic animals found within Kenshi. Fauna can be found roaming in packs or alone. They can also be found in Nests or living in abandoned ruins. Nests often contain eggs and will send squads of their respective animals to attack the player's outpost if they are within range.
There are many types of fauna which can be purchased and kept as an Animal Player Character. More information on this can be found on Guide to Animals.
