Omega-3 fatty acids are among the most evidence-supported supplements for cats. Here is what they do and how to use them.
Benefits of Omega-3 for Cats
- Reduces inflammation — beneficial for arthritis, allergies, IBD
- Supports coat and skin health
- Supports heart health
- May support kidney function
- Supports brain development in kittens
Best Sources
- Fish oil (salmon oil, sardine oil): richest source of EPA and DHA
- Whole fish in the diet: sardines, mackerel, herring
- Algae-based omega-3: plant-based EPA/DHA source
What to Avoid
Cod liver oil contains vitamins A and D that can reach toxic levels at high doses. Stick to body oil (salmon oil, sardine oil) rather than liver oil.
Dosing
General guideline: 40mg EPA+DHA per kg body weight daily. A 4kg cat would need approximately 160mg EPA+DHA. Always check product labels for actual EPA+DHA content.
Supplement Quality
Choose products with IFOS certification or AAFCO compliance. Rancid fish oil is worse than no supplementation.
