Is Onion toxic to cat?
All onion species are toxic to cats, with the onion (Allium cepa) being the most toxic of them all. Every part of the plant, both above and below ground, is poisonous to felines. A cat that has eaten some will start to show signs of illness - which may include vomiting, excessive drooling, diarrhea, weakness, pale gums and/or abdominal pain - within 6-12 hours. Often, cats require veterinary treatment to fully recover. Even cooked onions are hazardous!
Is Onion toxic to dog?
All parts of the onion plant are at least mildly toxic to dogs, but it is the bulb - the part most commonly prepared and eaten by humans - that typically causes the strongest reactions. Dogs often accidentally eat onions that are cooked in dishes they are given as table scraps. Vomiting, diarrhea, excessive drooling, and general gastrointestinal distress are all possible results. While these symptoms all may cause great discomfort to your pup, onion ingestion, thankfully, almost never causes severe or fatal reactions.
