Can my cat eat a couple of frozen blueberries with the skin on, or should I thaw and peel them first?

Short answer

Yes, your cat can eat a couple of frozen blueberries with the skin on — the skin is safe and contains beneficial antioxidants. Frozen berries can be a refreshing treat, but make sure they are washed and free of any added sugars or preservatives. Thawing isn't necessary, but offering them frozen whole poses a slight choking risk for some cats, so you might want to slightly thaw and mash them or supervise closely. As with any treat, keep the portion small to avoid digestive upset.

A safe, healthy treat — washed and whole. Good source of antioxidants.

Dogs and cats carry the same rating (Safe to share), so the notes below hold for either pet.

Blueberry is not toxic to cats. The real limit is calories, fat and salt, so treat it as a small extra alongside the normal ration rather than a meal in itself.

There is no poisoning risk here, and the usual problem is simply eating too much at once: a heavy fat or salt load can bring on loose stools or a single vomit. Offer water, keep an eye on the pet for 24 hours, and do not induce vomiting.
