My cat ate about half a cup of cooked spaghetti squash last night and seems fine — what should I watch for over the next 24 hours?

Short answer

Your cat is fine; cooked spaghetti squash is safe for cats. Since it's a new food, watch for mild digestive changes like softer stool or a bit of gas over the next day — that's the most likely reaction. If you see vomiting, lethargy, or any signs of pain, call your own vet to be safe, but a simple vegetable like this rarely causes problems when served plain.

Spaghetti squash — Food safety facts

Cooked plain and cooled.

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

Spaghetti squash 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.
