The ratio of omega-3 to omega-6 fatty acids in your cat's diet influences the overall inflammatory balance in their body. Omega-6 metabolites generally promote inflammation (necessary for healing and immune response), while omega-3 metabolites dampen it. Most commercial cat foods and meat-based diets are heavily weighted toward omega-6, with ratios of 10:1 to 20:1 being common. While cats need both, shifting toward a lower ratio (closer to 5:1 or less) may benefit cats with inflammatory conditions.
An ideal omega-6:omega-3 ratio for cats is approximately 5:1 to 10:1. Most commercial cat foods fall in the 10:1 to 20:1 range. Adding a small amount of fish oil or feeding oily fish like salmon or sardines a few times per week can help improve the ratio without complex calculations.
An imbalanced ratio is not a deficiency per se, but a chronically high omega-6:omega-3 ratio may manifest as persistent inflammatory skin conditions, worsening allergies, and joint stiffness.
Excessive omega-3 relative to omega-6 (extremely rare in practice) could theoretically impair necessary inflammatory responses and wound healing. This is not a realistic concern with normal feeding practices.
