I have some good ideas on how to do this stuff and may be implementing some rudimentary taming (after I’m done with z-levels).
For one, it would be cool to feed dogs and cats with real food items rather than some magical dog/cat taming food.
Currently pets are kinda useless because they are suicidal, can’t be healed and pretty much only just attack. It will take some AI enhancements to make them properly do things like leading zombies away, mauling corpses so that they don’t raise back, fetching small items you point at etc.
