Why does animal vomit?

Animals vomit as a natural response to various factors, including the ingestion of spoiled food, toxins, or irritants that upset their stomachs. It can also occur due to motion sickness, stress, or underlying health issues. Vomiting helps expel harmful substances, providing a protective mechanism for the animal. Additionally, some animals may vomit to clear their stomachs before eating again, especially in the case of scavengers.
