Pet AI is a Vintage Story mod by Gerste. Pet AI is a library of behaviors and tasks for tameable creatures. It has no effect by itself and supports other mods that add domestic animals.

Why this mod is worth installing
This dependency is useful for players who install taming mods built on its framework, and for creators designing custom pets. It is not needed in an unmodified world.
What Pet AI adds
Pet AI provides reusable AI behaviors and tasks for domesticating animals, including obedience and hand-feeding interactions. The framework is intended to give other creature mods a shared foundation instead of implementing taming logic separately.
On its own, the library does not create animals, pets, or new gameplay objects. Compatible additions can use it to control taming speed, growth, obedience loss, and whether owners or other players can damage pets.
Animals using this system are fed by hand to improve obedience rather than through feeding troughs. They do not starve simply because they are not fed regularly, unless another mod changes that rule.
