Can cats eat onions? - in detail

Cats should not consume onions due to their toxic effects on felines. Onions contain compounds called disulfides and thiosulfates, which are harmful to cats. When ingested, these compounds can cause damage to red blood cells in cats, leading to a condition known as hemolytic anemia. Symptoms of hemolytic anemia in cats may include lethargy, weakness, pale gums, and increased heart rate. In severe cases, it can even be fatal. Additionally, onions contain thiosulfates, which can cause gastrointestinal upset in cats, leading to symptoms such as vomiting and diarrhea. It is important for cat owners to be aware of the potential dangers of feeding onions to their pets and to ensure that any food given to cats does not contain onions or related vegetables like garlic, chives, and leeks. If a cat has ingested onions, it is crucial to seek veterinary care immediately to prevent potentially serious health complications.
