Between mulberries and grapes, which is the safer fruit for my 5kg indoor cat if I want to give a tiny snack?

Short answer

Yes, mulberries are the safer option for a cat compared to grapes, which are known to be highly toxic. Ripe mulberries can be offered in very small numbers, such as a couple of berries, and they are generally well tolerated. Grapes, even in tiny amounts, can cause rapid kidney failure in cats and should never be given. Serve the mulberries plain, without added sugar, and watch for any signs of vomiting or diarrhea; if anything seems off, contact your regular veterinarian.

Ripe berries are safe in small numbers. Unripe fruit and the leaves are not.

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

Mulberry 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.
