Q. My cats ate a small amount of chives, how worried shoul I be?
A. Chives are toxic to cats. Please call your veterinarian as soon as possible or the pet poison helpline:
24/7 Animal Poison Control Center
Onions, garlic, chives, and leeks are of the Allium family, and are poisonous to both dogs and cats. Onion and garlic poisoning results in oxidative damage to the red blood cells (making the red blood cells more likely to rupture) and gastroenteritis (e.g., nausea, oral irritation, drooling, abdominal pain, vomiting, diarrhea). Other clinical signs of anemia may be seen, and include lethargy, pale gums, an elevated heart rate, an increased respiratory rate, weakness, exercise intolerance, and collapse. Onion and garlic poisoning may have a delayed onset, and clinical signs may not be apparent for several days.
