Austin And Kat Expands Its Functional Mushroom Line With Powders And Concentrated Extracts

(PRESS RELEASE) SEATTLE, WA — Austin and Kat, the Seattle-based, 100% employee-owned pet wellness brand, has expanded its functional mushroom collection with three whole-mushroom powders and two concentrated liquid extracts for dogs. The expansion extends the in-house, small-batch approach that built the company’s CBD line into one of the fastest-growing categories in pet wellness, and one where ingredient quality varies widely.

Austin and Kat started in 2014 with hemp chews Kat Donatello made in her kitchen for her own dogs. More than a decade later, the company formulates, sources, and handcrafts everything it sells at its NASC-certified Seattle Makery, from CBD + CBDa chews to omegas and now a complete functional mushroom line. The throughline has not changed: know every supplier, test every batch, and make nothing the team would not give its own dogs.

“Mushrooms are where my obsession with sourcing really shows up,” said Kat Donatello, founder and CEO. “The species matters, the parts of the mushroom matters, and how it is grown and extracted matters even more. We were not willing to put our name on a mushroom product until we could stand behind every step of it. Now we can, and I am proud of what we built.”

That standard extends to sourcing. Austin and Kat makes its mushroom products with organic, whole-mushroom ingredients from M2 Ingredients, a Southern California company and North America’s largest grower of functional mushrooms. M2 cultivates and processes everything in the United States at its Vista, California facility, a rarity in a category still dominated by imported mushroom biomass of uncertain origin. Its full-spectrum ingredients capture the entire mushroom rather than isolated fractions, which is exactly what drew Kat to the partnership.

The expanded line comes in two formats. Three whole-mushroom powders lead with single-species Turkey Tail and Lion’s Mane, made with 100% active ingredients and no fillers, alongside 7 Mighty Mushrooms, a seven-mushroom blend meal topper. Gently dried to preserve naturally occurring beta-glucans, the powders are formulated to support immune balance, digestive wellness, and everyday vitality.

For pet parents who prefer a liquid, two concentrated extracts round out the line: Lion’s Mane Extract, formulated to support cognitive function and healthy nerve signaling, and 6 Mighty Mushrooms, a six-species blend for daily immune and digestive support.

Austin and Kat’s functional mushroom powders and extracts are available now to retailers through austinandkatwholesale.com and through the company’s distribution partners, including Pet Food Experts, Southeast Pet, Independent Pet Supply, IPS South, and Sunburst Pet Supply, as well as directly from Austin and Kat. Suggested retail is $29.95 across the line.

“Interest in functional mushrooms is growing fast, and ingredient quality varies more than most shoppers realize,” said Lilly Miller, Director of Education at Austin and Kat. “What I love about this line is that it gives retailers something honest to talk about: whole mushrooms backed by a growing body of research, made by the same people who answer the phone.”
