Can Cats Eat Sardines?
Yes — plain sardines can be safe for cats in small amounts. They should be an occasional treat, not a regular diet, and the safest choice is sardines packed in water with no added salt or seasonings.
Plain sardines are usually safe for cats in small amounts
A bite or small portion of plain, cooked or canned sardines packed in water is usually low risk for healthy cats. Problems are more likely if the sardines are salty, packed in oil, heavily seasoned, or fed often enough to unbalance your cat's diet.

How to Safely Feed Sardines to Your Cat
Sardines can be an occasional treat for cats, but they should not replace a complete and balanced cat food. Choose simple preparations and keep portions small because cats are sensitive to dietary changes, extra fat, and excess sodium.
- Choose plain sardines packed in water with no added salt whenever possible
- Avoid sardines packed in oil, mustard, tomato sauce, hot sauce, garlic, onion, or other seasonings
- Feed only a small taste or a few bite-sized flakes for most cats as an occasional treat
- Treats, including sardines, should stay within about 10 to 15 percent of your cat's daily calories
- Cooked or canned sardines are safer than raw fish; raw fish can carry infectious risks, and raw freshwater fish contain thiaminase
- If your cat has kidney disease, heart disease, pancreatitis, or suspected food allergies, call your vet before offering sardines
