Can plain cooked millet cause diarrhoea or an itchy skin reaction in a cat with food sensitivities?

Short answer

While plain cooked millet is generally safe and gluten-free, any new food can trigger an intolerance in a sensitive cat. The sudden introduction of fiber or a novel ingredient might lead to temporary digestive upset like gas or loose stools. True food allergies to millet are rare in cats, but itchy skin or ear infections are possible signs if an allergy does exist. Start with a tiny spoonful mixed into their regular food, watch for any changes over the next day, and call your own vet if symptoms like persistent diarrhea or scratching appear.

Cooked plain millet is safe and gluten-free.

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

Millet 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.
