The fainting goat, also known as the Myotonic goat, is a domestic breed known for its unique reaction to sudden stimuli. When startled, these goats experience a temporary condition called myotonia, which causes their muscles to stiffen and can lead them to fall over. This reaction typically lasts for about 10 seconds, after which they regain their mobility. Fainting goats are medium-sized animals with a friendly temperament, making them popular as pets and farm animals. They are often raised for their meat, milk, and fiber, and their distinctive fainting behavior has made them a favorite attraction at fairs and petting zoos.
