Interesting, but I don't think that's a way of increasing acceptance. Most of the items listed seem to be either babies of the same species, or females to attract males
I read somewhere that you can manually feed certain items of food to animals, like fruit and veg, in order to gain their trust (I'm particularly interested in cows as I have an "Agitated" bull that doesn't seem to want to calm down).
I'm a few months into my save, in the middle of winter, so I can't find or forage fresh fruit and veg. Are there any other foods that might work? Is there a way of finding a definitive list?
