Cat food bowl
If you buy sardines in large -- 15 oz. 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.
Sardines are a wonderful, healthy food to give your cat for an occasional treat. Not only will your cat love the yummy fish, 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 preparation of sardines from the many choices in your grocery store, there are guidelines to help you choose the correct fish to feed your favorite feline.
Select the right kind of sardines. Packaged in a variety of liquids and flavored sauces including cream, tomato sauce and mustard, sardines packed in water are best for your cat. Sardines in oil will also work in moderation -- and your kitty gets an extra helping of oil. Avoid sardines in sauce, as the salt content tends to be high, and there may some ingredients harmful to cats, such as onion and garlic. Fresh, frozen sardines are a great alternative. Thaw the fish, chop it finely or pulse it in a food processor to make a yummy paste.
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; the bones are soft enough for your cat to chew, but chopping up the fish is a good idea for easier digestion.
