Is Salmon Oil Good for Cats?

Is Salmon Oil Good for Cats

Yes, salmon oil for cats is an excellent choice. Salmon oil contains essential fatty acids like omega-3 and omega-6. They reduce inflammation in the body and improve the cat’s skin and coat.

Salmon oil for cats works on different body systems and comes with several health benefits. In simple terms, salmon oil supports the cardiovascular and musculoskeletal systems. It also boosts cognition, helps maintain healthy body weight, and prevents hairballs.

What are the Benefits of Salmon Oil for Cats?

Salmon oil for cats works on several levels. Here are some of the benefits of adding salmon oil supplements to your cat’s menu:

  • Joint Support. Salmon oil contains EPA and DHA (long-chain polyunsaturated omega fatty acids) with potent anti-inflammatory features. They are particularly beneficial for arthritic cats with achy joints.
  • Heart Protection. Salmon oil helps prevent heart disease as its constituents reduce the levels of triglycerides (a type of crude fat linked with cardiovascular issues). It also works as an anticoagulant.
  • Skin Health. Salmon oil helps relieve dry and flaky skin. The omega-3 and omega-6 fatty acids are great for skin and coat health. Low levels of omega acids lead to skin issues – irritation and itchiness.
  • Kidney Function. Fish oil reduces high blood pressure and decreases protein loss in the urine. It also limits the production of pro-inflammatory chemicals that can damage the kidneys and cause kidney disease.
  • Better Cognition. Salmon oil is known to improve cognitive function, especially in older cats. It was also responsible for decreasing pattern-pacing behaviors. This is thanks to the DHA content.
  • Weight Management. Omega-3 fatty acids control the plasma insulin levels and help control certain metabolites associated with weight gain. This reduces the risk of obesity, thus preventing many health problems.
  • Hairball Control. Improved overall skin and coat health due to salmon oil help reduce hairball formation and coughing. The healthier the cat’s skin and coat are, the less hair loss hence fewer hairballs.

Can Salmon Oil Make Cats Sick?

No, salmon oil cannot make cats sick when used responsibly. The supplement is considered to be extremely safe for cats.

However, if misused, it is linked with certain side effects. For example, if a cat consumes too much salmon oil, it will probably develop stomach upset (vomiting and diarrhea).

If your cat has been taking excessive quantities of oil for a prolonged period of time, it might develop a fishy odor, oily coat, and drowsiness. Since fish oil is high in calories, it can cause weight gain.

It is best to consult a vet before giving your cat supplements.
