A friend of mine has a goat that goes catatonic when it hears a loud noise. If she sneezes or the screen door slams. ..Then it tips over. Amazing but not uncommon. I had to learn more! They are classified as meat goats rather than milk goats…. but they might be better described as “pet goats”. Often selected as pets, due to their smaller stature, they are 17 to 25 inches tall and can weigh 60 lbs…. or more.
This ailment can be found in other animals, humans included.
A myotonic goat, otherwise known as the fainting goat, is a domestic goat that freezes for roughly 3 seconds when it feels panic. Though painless, this generally results in the animal collapsing on its side. The characteristic is caused by a hereditary genetic disorder called myotonia congenita. When startled, younger goats will stiffen and fall over. Older goats learn to spread their legs or lean against something when startled, and often they continue to run about in an awkward, stiff-legged shuffle. Fainting goats have many other names, including Myotonic Goats, Tennessee (Meat) Goats, Nervous Goats, Stiff-leg Goats, Wooden-leg Goats, and Tennessee Fainting Goats…. – Wikipedia
