Is half a cup of plain pumpkin seeds safe for my 3kg senior cat, or does its small size change the risk?

Short answer

Yes, plain unsalted pumpkin seeds are safe for cats of any size when offered in small quantities. A 3kg senior cat can enjoy a few seeds as an occasional treat without risk of toxicity. The seeds are low in fat and provide some fiber, but they are hard to chew, so monitor for choking. Offer only a pinch at a time and watch that the cat swallows them whole. If you see vomiting, diarrhea, or difficulty breathing, give your vet a call.

Plain unsalted pumpkin seeds are safe in small amounts.

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

Pumpkin seeds 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.

Why these cautions matter

A heavy salt load drives up thirst and urination, and in the worst cases leads to sodium ion poisoning, which is a genuine emergency.

Stone-fruit pits and some seeds release cyanide when crushed, and quite apart from that they are a choking and blockage hazard.
