The Role of Arachidonic Acid in Feline Health

Is arachidonic acid essential for cats?

Yes. Cats have limited ability to make arachidonic acid from linoleic acid, so they require dietary sources. Complete-and-balanced commercial cat foods are formulated to meet this need.

Can my cat get arachidonic acid from plant oils like sunflower or safflower oil?

Plant oils provide linoleic acid, not preformed arachidonic acid. Because cats convert linoleic acid to arachidonic acid poorly, plant oils are not a reliable way to meet ARA requirements.

If I feed fish-based food or add salmon oil, does that cover arachidonic acid?

Fish oils mainly provide EPA and DHA (omega-3 fatty acids). These can be beneficial for certain conditions, but they do not replace arachidonic acid needs. A balanced cat food should still supply ARA from appropriate ingredients.

Do I need to supplement arachidonic acid?

Most cats eating a reputable complete-and-balanced diet do not need ARA supplementation. Supplementing fats without a clear reason can add excess calories or unbalance the diet. For homemade diets, work with a veterinarian or board-certified veterinary nutritionist to ensure the recipe includes appropriate essential fats.

What are signs my cat might not be getting enough essential fatty acids?

Possible signs include dry or dull coat, scaling, or poor skin quality, but these are not specific and often have other causes (fleas, infections, allergies). If you suspect a diet issue, bring your cat and the exact diet details (brand, recipe, treats, supplements) to your veterinarian for a targeted plan.

Are omega-6 fats “inflammatory” and harmful?

Omega-6 fats are essential. Arachidonic acid supports normal immune signaling and tissue health. The practical goal is a balanced, species-appropriate diet and appropriate total calories, not eliminating omega-6 fats.

Best next step: If you’re considering a new food, homemade diet, or supplements (especially oils), consult your veterinarian for individualized guidance based on your cat’s age, body condition, and medical history.
