For anyone wondering like I was on why it’s not eating the berries you put in it’s inventory after it’s been tamed is because yes they do still need the vegetable cake. As soon as I put the cake in its inventory it started eating it.
If you are considering breeding these, go slam your hand in a car door a few times. It will be much less painful. Literally one veggie cake per percent of growth....and it grows slow.. Digests roughly one point of food per second, so feed a cake about one for every 7 mins (during event boost) and it will gain one percent of growth.
