When a white horse is not a horse

When a white horse is not a horse, it means that the animal is not a real horse. A white horse might look like a horse, but it is really a completely different animal. It could be a zebra, donkey, or another type of animal. The color of their fur might make them look like horses, but their bodies, hooves, and other features will be different and usually won't be the same as a real horse. That is why a white horse is not a horse.
