Question: what do horses do when alone

Get lonely… Horses are prey animals and they feel vulnerable when they’re alone (even though we know there’s no predators). Having friends is incredibly important to them and they spend a lot of time being affectionate with each other normally. When they’re on their own they sleep less because they don’t feel safe and some will start doing abnormal things like pacing or weaving as a way to cope with the stress. Some will even bite themselves and hurt themselves because they’re so frustrated. They all tend to call a lot when on their own to try to find other horses to be with. Some of them eat more because there’s nothing else to do but others will stop eating because they’ve no-one to look out for predators while they eat and they’re too stressed.
