Chronic Kidney Disease
Omega-3 fatty acids help reduce the production of inflammatory compounds that create oxidative stress to the tissue of the diseased kidneys, thus contributing to slowed progression of Chronic Kidney Disease in cats. This works by reducing protein 'leaking' through the kidneys, which is a common symptom called Proteinuria, which contributes to weight loss in a CKD cat.

Other benefits of an Omega 3 Fish Oil supplement for cats are:

Skin Allergies and Skin Disease
Fish oil is commonly given to cats with allergic or inflammatory skin disease. It can help reduce itchiness and dandruff by decreasing the production and release of inflammatory stimulators called cytokines and improve a cat’s dry, flaking skin.

Arthritis and Joint Disease
For cats with arthritis, fish oil can help decrease inflammation in the joints. Studies show that cats given both EPA and DHA supplements in their diet, along with green-lipped mussel (a glucosamine/chondroitin source), had a noticeable improvement in their mobility.

Heart Disease
Fish oil can help lower and regulate a cat’s heart rate, thus lowering the risks of atrial fibrillation (a potentially fatal heart arrhythmia). Omega fatty acids for cats are also thought to help decrease triglycerides in the body, which can contribute to heart disease in cats. Fish oil may also help prevent blood clots.

Inflammatory Bowel Disease (IBD)
Fish oil is known to decrease potentially harmful triglycerides and promote less inflammation, which can help with both inflammatory bowel disease and pancreatitis in cats.

Epilepsy, Seizures and Brain Health
DHA is important for promoting brain health and development in cats. For this reason, fish oil for cats has been shown to be helpful both in developing kittens and in older felines with cognitive dysfunction.

Diabetes and Obesity
Diets containing DHA and EPA have been known to help make insulin more effective in obese cats with or without diabetes. This helps decrease body fat and allows cats to use glucose more effectively when they have diabetes. In overweight cats without diabetes, fish oil has been associated with decreasing the risk of developing diabetes.

Cancer
DHA has an ability to shrink tumors, and studies have shown that it can help work against cancer by not allowing cancerous cells to divide.

Manufacturer's Info
Caution should be taken when choosing an Omega 3 Fish Oil as a supplement for your cat, as not all Omega 3 Fish Oils are alike, and some can even be considered unhealthy. Nordic Naturals is not cold pressed, but instead uses molecular distillation (used for all of their fish oil products) which removes environmental toxins like mercury and other heavy metals, dioxins, etc., saturated fats, and other undesirable organic compounds, leaving behind only the key beneficial components of the fish oil. It is a gentle distillation process with exceptionally low heat residence time, and is performed in a vacuum to further reduce the heat requirement. Flash distillation (used for their non-concentrated fish oils) accomplishes the same thing as molecular distillation, but utilizes steam rather than a vacuum.
