Most cats take well to the taste of this oil, as they are attracted to the scent of salmon. It offers all the benefits that Omega 3’s has to offer and is a great source of EPA and DHA.
The only downside that reviewers complained of was the strong fish smell, which is typical of fish oils, though some manufacturers do try to eliminate the stronger scent. This product is made in the USA and is backed with a satisfaction guarantee.
2. American Journey Wild Alaskan Salmon Oil – Best Value

Buyer’s Guide: Choosing the Best Fish Oil Supplements for Cats
Checking ingredients is the most important part of choosing a supplement for your cat. With Omega 3 fish oils, you want a product that contains EPA and DHA. You also want to ensure your fish oil is not made with any unnecessary ingredients or harmful toxins. Because this is coming from fish, ensuring the oil has been distilled for purity and to remove mercury, pesticides, and dioxins.
Fish oil supplements can come in both liquid and pill forms. As you can see, liquids are more common but both types are relatively easy to come by. You will want to choose the type of Omega 3 fish oil that your cat will tolerate best.
Some cats may consume the fish oil liquid with ease, while others may turn away. This is dependent on your preference and that of your animals. Liquid can be conveniently added to your cat’s food and may even entice them more.
Liquids can also be messier, and you run the risk of faulty pumps and bottle leaks. It’s no fun having an oil mess to clean up, and some of the oils still have that unpleasant fishy smell.
Supplements are not regulated in the same way that conventional drug and food products are. Keep a close eye on the testing done for supplements such as Omega 3 fish oils. If a product has been independently tested by a third party for purity, that can provide you more certainty that you are getting a well-rounded, high-quality product.
NASC Quality Seals can be found on brands that meet strict requirements regarding quality. Also, research the manufacturer and look and see if they offer satisfaction or money-back guarantees on their products.
Fish oil can be a pricey supplement. You will want to ensure you are getting good value for your money. Some oils can be expensive and only contain a small amount of liquid, while others can have much more in quantity and still offer a great value. Be sure to check bottle size for liquid supplements and dosage and quantity for pills. Keep in mind that products that get additional testing and go through strict quality processing may come at a much higher price. It can be well worth the extra cost to get a great quality fish oil.
Benefits of Supplementing with Omega 3 Fish Oil Supplements
Zesty Paws Core Elements Wild Alaskan Salmon Oil not only comes at a reasonable price for the quantity but is a very well-reviewed fish oil complete with DHA and EPA and made from pure wild Alaskan salmon oil.

Now that you know what the reviews have to say and are aware of the considerations to keep in mind while shopping, you should be well on your way to finding the right fish oil supplement for your cat.
