Jas claims to have fed a crawdad to a cow.
According to Wikipedia, a crawdad is just another name for a crayfish. Since you can catch crayfish in the game, I thought that my bovine companions would be delighted to receive one as a treat. However, when I left or right-click the cow while holding a crayfish, the cow's status box pops up and I can't seem to find a way to hand over the crustacean.
Is Jas just a big fat liar? Can I actually feed crayfish (and potentially other strange things) to my cow? If so, what effect does it have?
