What It Does
Builds and maintains your pet's skin barrier — the waterproof shield that keeps moisture in and irritants out. Linoleic acid produces ceramide (the "glue" between skin cells) and is essential for reproduction and growth. Cats also need arachidonic acid (AA), which they cannot produce from linoleic acid unlike dogs.
What You’ll Notice
A healthy omega-6 level means no dandruff, a supple skin when you part the fur, and minimal shedding. Deficiency causes dry, flaky skin, a coarse coat, and slow wound healing. The key is the ratio — omega-6 to omega-3 should ideally be 5:1 to 10:1.
Supple skin
No dandruff

Sources & Notes
Poultry fat, sunflower oil, vegetable oils. Most commercial pet foods have adequate omega-6 — the bigger concern is too little omega-3 to balance it.
