Cats can eat rice, but only in small amounts and as an occasional treat. Rice is not toxic to cats and can be safe if it is well-cooked, plain (without butter, spices, or seasonings), and fed alongside a balanced commercial cat food. However, rice is not nutritionally necessary for cats since they are obligate carnivores and primarily need meat in their diet. Overfeeding rice or other carbohydrates can contribute to obesity and related health issues like diabetes. Additionally, uncooked rice should be avoided as it is difficult to digest and may cause digestive upset. Brown rice may offer a slight nutritional advantage over white rice but still should be given sparingly. Always consult a vet before introducing rice or any human food into a cat's diet.
