For the first time, I know what a mineral stone was. Right after seeing it, all the cows were eager to lick it. In the past, they could only lick the floors. This kind of stone contains minerals, helping the animals stay healthy, grow fast and look beautiful. Other villagers have been excited to see the mineral stones working so well with my cattle and plan to order them for their own cattle.
