Omega-6 fatty acids (primarily linoleic acid) support skin barrier function, coat health, and cellular growth. Most diets naturally provide adequate omega-6 without any effort, as it is abundant in seeds, grains, and even hay. For rabbits, the concern is not deficiency but potential excess — too much omega-6 relative to omega-3 can promote inflammatory responses. Since rabbits eat a naturally low-fat, herbivorous diet, omega-6 intake is typically well-balanced and not a practical concern.
A single sunflower seed contains about 3mg of linoleic acid (omega-6) — your rabbit's natural diet of timothy hay and greens provides adequate omega-6 without supplementation. The key is maintaining a balanced omega-6 to omega-3 ratio by keeping seed and nut treats to an absolute minimum.
0.35% of daily nutrient intake
Omega-6 Fatty Acids makes up 0.35% of your domestic rabbit's total daily nutritional requirements by weight. That's a tiny amount — but it matters.
True omega-6 deficiency is extremely unlikely in rabbits eating any reasonable diet. Theoretical signs would include dry skin, poor coat condition, and impaired wound healing.
Excess omega-6 can promote chronic low-grade inflammation. In rabbits, this is mainly a risk if fed too many seeds or nuts, which are concentrated omega-6 sources. A seed-heavy diet also contributes to obesity.

The balance between omega-6 and omega-3 fatty acids influences inflammatory responses throughout the body. Omega-6 tends to promote inflammation while omega-3 has anti-inflammatory effects. In rabbits, a natural hay-and-greens diet provides a reasonably balanced ratio, but feeding excessive seeds or nuts skews the balance heavily toward omega-6, potentially promoting chronic low-grade inflammation.
What this means: Keep seeds and nuts to an absolute minimum — no more than a few per week as rare treats. The natural omega-6 to omega-3 ratio in timothy hay and leafy greens is well-balanced and appropriate for your rabbit's needs without supplementation.
