Cats can have blueberries safely in small amounts as an occasional treat. Blueberries are non-toxic to cats and can provide some benefits like antioxidants, fiber, and vitamins, but since cats are obligate carnivores, their digestive systems are designed primarily for meat. Therefore, blueberries should only be given sparingly and not as a regular part of their diet. It is important to wash the berries first and avoid sweetened blueberry products. Too many blueberries may cause digestive upset or blood sugar spikes, especially in diabetic cats. Kittens should be introduced to fruit treats with caution and usually only after they are older. Whole blueberries could also be a choking hazard for small cats or kittens.
