Can Cats Drink Oat Milk?

Safe in small amounts — Oat Milk for cats.

Safe in small amounts

Why: Plain unsweetened oat milk is not toxic to cats. It is mostly water and oats, so a small amount is harmless — but flavoured or sweetened oat milks often contain sugar, flavourings or xylitol, which are not safe.

Safe serving: A tablespoon or two of plain unsweetened oat milk, occasionally. Check the label for xylitol first.

If your cat ate oat milk: No action needed for plain oat milk. If it was sweetened with xylitol, call your vet immediately.
