Yes. Sardines are one of the best fish treats for cats — small, oily and low in mercury.

Why it’s fine

Because sardines are small, short-lived fish, they accumulate far less mercury than tuna. They provide omega-3 fatty acids for skin and coat, quality protein, and calcium from the soft bones, making them a genuinely nutritious occasional treat.

How to serve it safely

Offer one or two sardines packed in water with no added salt, once or twice a week. Skip varieties in oil, brine or tomato sauce.

When to call the vet

Call your vet only if repeated vomiting or itching follows fish treats — rare fish allergies do occur.

Common questions

Can cats eat the little bones?

Yes. Sardine bones are soft and edible once packed, and they are a good calcium source — no need to pick them out.

What about sardines in tomato sauce?

No. That version adds salt, sugar and acidity. Water-packed is the only kind worth sharing.
