Fruits
Can cats eat blueberries?
Non-toxic, low-calorie and bite-sized, which makes them one of the better fruit treats.
Portion: 1–3 berries, a few times a week at most.
The short answer
Yes. Blueberries are non-toxic to cats and are among the lowest-risk fruits to share. They're low in calories and small, though whole berries can be a choking risk for gulpers, so halve them. One to three berries occasionally is a sensible limit. Blueberries appear in some commercial cat foods, but in small amounts. Your cat gets no real health boost from eating them.
Why the verdict
Blueberries contain antioxidants, fibre and a little sugar, and nothing known to be toxic to cats. Because cats can't taste sweetness and are obligate carnivores, the benefit is minimal. Too many can cause loose stools from the fibre.
How to prepare it
- Wash well.
- Halve or squash them for small cats and kittens.
- Fresh or plain frozen (thawed) only.
- No blueberry muffins, jam, yogurt or pie.
Signs of trouble
- Loose stool
- Vomiting (rare)
- Choking or gagging on a whole berry
