Blueberries are generally safe for cats to eat in small quantities as an occasional treat. They are not toxic to cats and can provide some health benefits such as antioxidants, fiber, and being low in calories. However, cats are obligate carnivores and do not need fruit in their diet. Feeding too many blueberries may cause digestive upset like diarrhea or vomiting, and the sugar content can be problematic, especially for cats with diabetes or obesity. Also, whole blueberries might be a choking hazard for small cats or kittens. It is best to wash blueberries thoroughly before offering and to feed only a few as treats, not exceeding 10% of their diet. In summary:
- Blueberries are safe in small amounts and can be a low-calorie, antioxidant-rich treat.
- Cats do not need blueberries for nutrition and should eat mostly meat-based food.
- Overfeeding blueberries can lead to digestive issues and blood sugar spikes.
- Avoid giving processed blueberry products like muffins or extracts due to harmful ingredients.
- Always offer fresh, washed blueberries and introduce gradually.
This guidance applies mainly to healthy adult cats; kittens and cats with health conditions should be given blueberries only after consulting a veterinarian.
