My cat just ate a few ripe mulberries, not grapes. Are mulberries safer for a 12-year-old cat with kidney issues?

Short answer

Yes, ripe mulberries are much safer than grapes for any cat, including seniors with kidney concerns. Grapes are highly toxic and can cause sudden kidney failure, but mulberries are non-toxic and safe in small amounts. Offer your cat some fresh water and watch for any unusual signs like vomiting or diarrhea. Call your own vet if anything seems off.

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.
