Cats can eat cilantro safely in small amounts. Cilantro is not toxic to cats and can be given as an occasional treat or supplement to their diet, but it is not necessary for their nutrition since cats are obligate carnivores and do not require plant foods. Some cats might enjoy nibbling on cilantro leaves or stems, while others may not be interested because of its strong flavor. It is important to introduce cilantro in small quantities to monitor for any digestive upset or allergic reactions like vomiting, diarrhea, or skin irritation. Cilantro can provide some nutritional benefits such as vitamins A, C, K, antioxidants, and fiber, which may aid digestion and hydration if tolerated well by the cat. However, it should never replace their regular commercial cat food. Consulting a veterinarian before regularly feeding cilantro to cats, especially those with health issues or on medications, is recommended.
