5 Best Fish Oil Supplements for Cats in 2023

5 Real Benefits Of Fish Oil For CatsIt is not uncommon for cats to lose hair, itchy skin and persistent joint pain as they age. The main cause of deteriorating health is usually low nutritional intake, which is why you must pay attention to your cat’s diet. Adding fats to a cat’s daily diet is more important than ever. In fact, fats provide cats with twice as much energy as protein and carbohydrates, making them a great source of a large number of nutrients. Fish oil is known for its numerous health benefits, and it’s not just humans who can benefit from it. Cats can also benefit from fish oil supplements, which provide essential omega-3 fatty acids that support their skin health, prevent heart disease and suppress inflammation.

How Much Fish Oil To Give A Cat Daily?

There is no exact recommended dosage for fish oil because your cat’s needs may vary depending on his diet and concurrent medical conditions. Dosing fish oil can be tricky as well because different formulas contain different concentrations of EPA and DHA.

 

There are several ways to determine dosage for fish oil:

 

Milligrams EPA + DHA per kilogram of body weight

Grams per 100g of pet food (as fed or dry matter basis)

Grams per 100 or 1,000 kcal of pet food

Ratio of omega-6 to omega-3

Catherine E. Lenox, DVM, and the American College of Veterinary Nutrition (ACVN) offer general dosing recommendations of 30 to 50 mg of fish oil per kilogram of body weight.

 

PetCareRX offers the following dosage recommendations:

 

Daily Dosage For Cats Over 2 Pounds

EPA DHA Total Long Chain Omega-3
35 mg 21 mg 71mg
69 mg 41 mg 143 mg
104 mg 62 mg 214 mg
138 mg 83 mg 285 mg
173 mg 104 mg 356 mg

 

It’s important to use fish oil supplements formulated specifically for cats, as some human fish oil supplements may contain ingredients that can be harmful to cats. Additionally, the dosage should be carefully monitored to avoid giving your cat too much fish oil, which can lead to vitamin E deficiency or other potential health issues.

FAQs

Q: What are the side effects of fish oil for cats?

A: Although fish oil is safe for cats, some felines may experience mild side effects such as diarrhoea, fatigue, skin flaking or vomiting. To be on the safe side, it is recommended that your cat starts with 1/4 of the recommended dose and then increases it to the full amount. Doing so will allow them to adapt better to the supplement and by starting with a small dose you will know if they should continue to take it.

 

Q: What type of omega-3 fish oil is best?

A: Fish oil supplements typically come in capsule or liquid form, though you may find them in soft chews as well. Look for a natural omega-3 supplement made with fish oil in its triglyceride form – the form your cat would naturally consume in pet food. Fish oil supplements made with synthetic oil (known as ethyl ester) contain high concentrations of EPA and DHA but they are more difficult for your cat’s body to absorb.
