Cows moo differently from region to region. In their own way, they mimic the farmer's dialect. Cows show their affection by licking each other on the head, shoulder, and back. When they are separated from their friends, they often become stressed and sad. Recognizing each other is not difficult for cows: their voices and scents are distinctive. Additionally, these animals can remember up to 100 faces from their herd and are very intelligent. They are not only capable of solving puzzles but also enjoy doing so. When they figure out how to open a gate with a button, they jump around and frolic with excitement.
