Look what happens to the cows and pigs forehead when you feed them. Here is how. Go to the small arrow in the small right hand corner. Then scroll down till you see hay bales. Then find a cow a *** or both. Touch then with the hay bale in your hand and thats how you feed them. Look at their foreheads when you do it a few times. A heart is suppose to show up in the middle of its eyes. Try it now.
