The Best Fish Oil for Cats Can Become An Ounce of Prevention

Giving Kitty a fish oil supplement is a pro-active step to ward off all manner of ills.

Not only does fish oil help to produce a sleek and shiny coat, it is a natural way to improve the skin health of cats.

More importantly, fish oil and the Omega 3 fatty acids therein improve your cat’s immune system and reduce inflammation, and therefore discomfort, throughout Kitty’s body.

Fish oil is a natural warrior against many diseases including allergies, asthma, gastrointestinal diseases such as inflammatory bowel disease, arthritis, diseases of the immune system, and any kind of cancer. Unfortunately, your cat cannot produce Omega 3 fatty acids in her own body, and so we supplement.

….Or a Pound of Trouble

However, there are risks associated with fish oil supplements.

Even the best fish oil for cats can carry risks including allergic reactions, and can interfere with Kitty’s blood platelet production.

Remember that fish oil – or canned fish – has little or no nutritional value for cats.

Nevertheless, such goodies pack big-time punch in terms of empty calories and the risk of obesity. In some cases, there is also the potential for exposure to heavy metal poisoning.

Before you add a fish oil supplement, discuss the benefits versus the risks with Kitty’s veterinarian. Also get information about proper dosage.

Contrarily, some kitty owners attest that this is the only fish oil that they seem to like! Which one will it be?

Nordic Naturals state that this is a natural product and the ingredients are “derived from 100% wild, sustainable sourced anchovies and sardines.”

This product is the most expensive of the products we reviewed. A two-ounce bottle of this fish oil supplement retails for somewhere near 3 times the cost of others.

This supplement boasts that it is Made in America in an FDA approved facility. (Just in case you didn’t know, the FDA doesn’t inspect, approve, or otherwise qualify animal supplements. Nor does the FDA approve the place in which such supplements are made. This qualification may make you feel better, but is otherwise immaterial.)
