Here are some possible reasons why you might have heard or read about horses eating each other:
* Misinformation: There could be confusion or misinterpretation of an event. For example, a horse might have nibbled on another horse's mane or tail, which could be misconstrued as eating.
* Extreme circumstances: In extremely rare and dire situations, such as severe starvation or illness, a horse might resort to cannibalistic behavior. However, this is extremely unusual and not the norm.
* Animal abuse: Unfortunately, there are cases of animal abuse where horses may be starved or neglected to the point of resorting to desperate actions. This is a horrific situation and should be reported to the authorities immediately.
It's crucial to remember that horses are social animals and generally live in herds peacefully. They have a natural instinct to protect each other and wouldn't engage in harming one another unless driven to it by extraordinary circumstances.
