Resilibiome Gut + Immune Health | Daily Probiotics for Cats

ResiliBiome Gut + Immune Health is a daily probiotic made by cats for cats. It features 5 strains, including 3 feline-origin strains, designed to support gut health, healthy stools, and overall wellness. Because the gut and immune system are so closely connected, consistent daily microbiome support can be a smart foundation for long-term feline health, especially for cats with sensitive digestion, stress-related changes, or inconsistent stools.

Why Species Specific Matters

The Feline Native Advantage

The Acid Test (Survival)

Most probiotics are destroyed by the high acidity of a cat’s stomach before they ever reach the gut. Our Feline-Native strains are lab-proven to survive at pH 2.0—the exact intensity of a healthy cat’s stomach.

Bile Resilience (Durability)

Even after the stomach, probiotics must survive bile salts—the body's natural "detergents." ResiliBiome stays active even in 5% bile concentrations, ensuring the formula actually reaches the gut alive.

Real Colonization (Activation)

Survival is only half the battle. Because our strains are host-derived, they arrive in the gut "awake" and ready to work immediately, rather than passing through your cat’s system dormant.

Proven "Sticky" Power (Adhesion)

In feline-specific lab tests, our strains showed an incredible 80% adhesion rate. They "anchor" to the intestinal wall to provide long-term resilience and immune support rather than just being washed away.

5 Strains, Prebiotics, Postbiotics + Beta Glucan

The Synergy Effect

ResiliBiome is designed for synergy, meaning each ingredient supports the others. The probiotic strains Lactobacillus reuteri KU-LR01 (feline-origin), Lacticaseibacillus paracasei KU-LP01 (feline-origin), Pediococcus acidilactici KU-PA01 (feline-origin), and Bifidobacterium animalis subsp. lactis are included to support a balanced gut microbiome. Saccharomyces boulardii adds a beneficial yeast to complement the bacterial probiotics. FOS and MOS act as prebiotics to help nourish beneficial microbes. Yeast 1,3/1,6 beta-glucans support healthy immune function, and the heat-treated Lactobacillus fermentate provides postbiotic-style support for overall gut and immune health. Together, this synergy supports daily gut + immune health more consistently than any single ingredient on its own.
