Omega-3 Feline Formula

Omega-3 Feline Formula

Meet your cat’s new daily essential: a pure, powerful omega-3 formula crafted just for felines. We start with wild-caught sardines and anchovies—small-but-mighty fish that deliver the cleanest, most concentrated omega-3 punch—then preserve their natural triglyceride form so every drop works harder. No fillers, no fluff. Just the essential fatty acids cats can’t make on their own, for everything from silky-soft coats to whole-body wellness.

Cats rely heavily on dietary fats to support skin health, coat condition, brain function, and overall health. The Omega-3 Feline Formula was developed specifically for feline metabolism, delivering essential fatty acids in a form that aligns with how cats naturally process nutrition.

This formula focuses on providing high-quality omega-3 fatty acids that support healthy skin, a soft and resilient coat, and normal cognitive and visual function.

Palatability is just as important as nutrition for cats. The oil is formulated to blend easily into food without overwhelming flavor or texture, allowing it to become a seamless part of the daily feeding routine. That ease of use supports consistency, which is where nutritional support becomes most meaningful.

A simple, reliable omega formula built specifically for feline biology and everyday use.

The stability of the oil matters.

We start with small, wild-caught fish and handle the oil carefully to protect the fragile fatty acids that support skin, joints, and cellular health. By sourcing responsibly and bottling in controlled batches, we reduce variability and help maintain the intended composition over time. Quality is determined by how the oil is sourced, protected, and preserved from oxidation, not simply by the amount of omega-3 listed on the label.

Austin and Kat was built differently from the very beginning. We are employee owned, female founded, and still led by the same hands that shaped the company from day one. Every formula is made by our own team in our own facility, not handed off to outside manufacturers. The people who craft these products are the same people who bring them home to their own pets, which keeps our standards personal, consistent, and accountable in a way that cannot be outsourced.

Cats don’t need complicated—they need real. Our formula stays intentionally simple, focusing on pure marine oils with feline-specific EPA and DHA ratios for maximum absorption. Gentle processing keeps the good stuff intact: rich fishiness they instinctively crave, and the potency their bodies thrive on. We’ve built this for cats, not “tiny dogs,” honoring their unique metabolism and carnivore biology.

  • Marine oils specifically chosen for feline preferences
  • Gentle processing preserves natural fish characteristics
  • Formulated for optimal feline omega-3 absorption

Science Behind The Scenes

Cats are obligate carnivores with very particular needs—Omega-3s are one of them. Our sardine + anchovy blend delivers EPA and DHA in the exact proportions that complement feline metabolism, supporting skin barrier function, coat shine, joint health, and even cardiovascular wellness. Because we skip unnecessary additives, there’s nothing to block absorption—just highly bioavailable omegas in their most natural form. And yes, we keep that fresh-caught aroma, because if your cat won’t eat it, it won’t work.

FAQs About This Formula

There are 1,472 mg of Omega-3 fatty acids per teaspoon.

Cats have unique nutritional needs that differ from dogs and humans. Our formula provides a naturally higher ratio of EPA to DHA (approximately 1.6:1) to support healthy skin and normal inflammatory pathways. EPA is known to help maintain the skin’s normal moisture barrier and plays a key role in supporting a healthy response to environmental stressors. This ratio reflects the specific balance of omega-3s most beneficial for cats, rather than the standard profiles formulated for humans. Many conventional fish oils prioritize general cardiovascular support, while our formula is designed with feline wellness in mind.

Oils containing animal-derived products (fish oils, green-lipped, mussel, etc.) should be used within 90 days of opening. 

All other formulas can be stored in a cool, dry place up to a year after opening.

We recommend refrigerating our oils only if you're not planning on finishing the bottle within 4-6 months of opening. (And oils with animal-derived ingredients should still be used within 90 days.)

Be sure to shake well before every use! 
Formulas containing coconut oil may need to come to room temperature to mix back together easily. 

Recycling: CBD Oil Bottles: Glass bottle and dropper are recyclable with other clean glass items. Remove and discard plastic tamper seal and labels from bottle. Separate glass dropper from plastic/rubber top (give the dropper a gentle wiggle & tug and it'll come right out.) Discard plastic/rubber dropper cap. 

All of our formulas are made with love, 100% by us. We do everything in small batches at our own Seattle MAKERY, and unlike most companies, we source all our own ingredients from start to finish.

You bet! We spare no expense when it comes to quality assurance and our commitment to small batch manufacturing truly separates us from the pack.

We follow a strict set of criteria to ensure that every ingredient is top quality with consistent purity and potency, testing for impurities and contaminants at multiple points along the way. It takes extra time and effort as our process starts well before the day of manufacturing, but every step is well worth it and gives us the confidence that we are delivering our best.
