Are ripe mulberries safer for my 4 kg cat than fresh raspberries, and how many can she have?

Short answer

Yes, both ripe mulberries and raspberries are safe for cats in small amounts. The main difference is that unripe mulberries and their leaves are not safe, whereas raspberry leaves are also considered potentially problematic. For a 4 kg cat, a couple of ripe berries as an occasional treat is fine, but more than that could upset her stomach due to the natural sugars and fiber. Always offer them washed and plain, and watch for any signs of digestive upset like soft stools.

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.
