The myotonic goat, also known as the fainting goat, is a breed of domestic goat known for its unique reaction to sudden stimuli. When startled, these goats experience a temporary muscle stiffness that can cause them to fall over, hence the name "fainting." This condition is due to a genetic disorder called myotonia, which affects muscle relaxation. Myotonic goats are medium-sized animals with a friendly temperament, making them popular as pets and for small-scale farming. They are also valued for their meat and fiber. Their distinctive behavior and gentle nature contribute to their charm and appeal among goat enthusiasts.
