How to feed cats sardines

Updated November 21, 2016

Sardines are a wonderful, healthy food to give your cat. Not only will your cat love the yummy fishy treat, but sardines are an excellent source of omega-3 fatty acids, which give your pet's immune system a boost and help prevent heart disease. Although it may be confusing to choose the most beneficial tin of sardines from the many choices in your grocery aisle, there are guidelines to help you choose the correct fish to feed your favourite feline.

Select the right kind of sardines. Packaged in a variety of liquids and flavoured sauces including cream, tomato sauce and mustard, sardines packed in water are best for your cat. Sardines in oil will also work -- and your kitty gets an extra helping of oil. If your only choice is sardines in sauce, read the ingredients and make sure onion powder is not on the list; onions are toxic to cats. Rinse off the sauce before feeding the fish to your cat.

Add sardines to your cat's dinner. An adult cat only needs one sardine a day in order to receive all the omega-3 fatty acid it needs for optimum health. Place the sardine on top of your cat's everyday food or chop it up with the kibble.

Make a sardine meal. Instead of feeding your cat one sardine a day, you can designate one meal per week as "sardine dinner" and feed your cat all the sardines it would normally get in a week's time. Replace the dry kibble with sardines; don't worry about the bones -- they're soft enough for your cat to chew with no ill effects, and add necessary fibre to its diet.


If you buy sardines in large -- 425gr. or larger -- quantities, freeze what you won't use in four or five days' time. The good fatty acids are lost if the sardines aren't used quickly after opening.
