Goats are quirky, rambunctious creatures full of spark; you might think they require a lot of shut-eye to recharge, but it's quite the opposite.
Goats do not sleep with their eyes open, though some people have observed kid goats with open eyes during REM sleep.
Kids can be seen with half-open eyes while in REM sleep; some animals can sleep with one or even both eyes open.
How do goats sleep? Goats lie down to sleep at night, not entirely on their sides, but more upright, making it easy to get up quickly when they need to.
