Your cat’s digestive system begins adjusting to ResiliBiome. Some cats may experience temporary softer stools before their stool quality becomes more consistent and well-formed.

By the second week, your cat’s gut environment may begin to feel more balanced. With daily use, ResiliBiome helps support stool quality, digestive comfort, and immune health.

Daily probiotic support helps maintain a healthier gut foundation for long-term digestive and immune wellness. This can be especially helpful in multi-cat homes, where shared spaces and everyday stressors may affect your cat’s gut balance.

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.

Stress Defense

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.

With the continually increasing incidences of chronic infectious diseases such as Feline Herpesvirus, Kitty Up has been a wonderful addition to our regimen. Cats really seem to love the product and it really helps to reduce the infectious burden.
