Best Omega-3 Fatty Acids-Rich Foods for Cats

Ranked by omega-3 fatty acids content among foods safe for cats in the Creature Feast catalog.

Salmon per 100g cooked: 1,500–2,500mg omega-3 Salmon is the premier omega-3 source for cats, providing both EPA and DHA in highly bioavailable forms. Wild-caught salmon tends to have higher omega-3 levels than farmed.

Canned Sardines per 100g: 1,000–1,500mg omega-3 Canned sardines are an affordable, convenient omega-3 powerhouse. Their small size means lower mercury accumulation compared to larger fish.

Tuna per 100g cooked: 200–700mg omega-3 Tuna provides omega-3s but in lower concentrations than salmon or sardines. Feed in moderation due to mercury concerns.

Granite Grit per 100g: 1,000–1,500mg omega-3 Sardines in water retain their full omega-3 content without the extra sodium of oil-packed varieties.

Eggs per large egg: 30–150mg omega-3 (varies) Eggs provide small amounts of omega-3s, especially omega-3 enriched eggs from hens fed flaxseed-supplemented diets.

Hemp Seeds per tablespoon: 1,000mg ALA omega-3 Hemp seeds provide plant-based ALA omega-3, but cats convert ALA to EPA and DHA very poorly. Marine sources are far more effective.

Chicken per 100g cooked: 50–100mg omega-3 Chicken provides small amounts of omega-3, mostly ALA. Pastured chickens have somewhat better omega-3 profiles than conventionally raised.
