Product Overview

About the Ingredients

Gut Rebuild for Cats features Peptacetobacter hiranonis (felis), a feline-specific probiotic strain considered a keystone species in the cat gut microbiome. Isolated from a healthy cat and validated through rigorous safety and efficacy trials by AnimalBiome’s team of microbiome experts, P. hiranonis (felis) converts primary bile acids into beneficial molecules that support healthy digestion and strengthen gut defenses.

Science-backed probiotic, Saccharomyces boulardii, and PreforPro®, a proprietary bacteriophage blend, work together to provide fast-acting symptom relief and support the colonization of P. hiranonis (felis) for restored microbiome balance.

Is this the right product for my cat?

Gut Rebuild is designed to promote more symptom-free days in cats with occasional or intermittent digestive issues. It supports deeper microbiome restoration than Gut Maintain for Cats, but is not a full ecosystem replacement like Gut Restore. 

Gut Rebuild is a powerful tool to help the microbiome recover from disturbances, especially antibiotic use, which can significantly reduce P. hiranonis (felis) levels. 

For cats with severe and longstanding digestive issues, Gut Rebuild can be used alongside Gut Restore for comprehensive microbiome restoration and symptom relief. 

Directions for Use

Administer 2 capsules per day

  • For very sensitive cats, you may start with one capsule per day and slowly transition up to two capsules per day. 
  • Gut Rebuild capsules can be administered whole, or they can be opened to mix the powder with food. 
  • The daily recommended amount of Gut Rebuild can be given together or at different times, with or without food. 
  • To maximize the benefits of Gut Rebuild, we recommend continuous daily use for at least 30 days.
  • Due to the living bacteria in Gut Rebuild, it is perishable once opened. Especially in warm or humid climates, we recommend storing in the refrigerator. 

Not for use in cats with chronic and severe constipation.

As with all supplements, consult with your veterinarian before use, especially if your pet has a health condition.

Storage Instructions

Store in a cool, dry place.
