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 Animal Biome’s team of microbiome experts, P. hiranonis (felis) converts primary bile acids into beneficial molecules that support healthy digestion and strengthen gut defenses.

The science-backed probiotic Saccharomyces boulardii, and the proprietary phage blend PreforPro® 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, 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, 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, give continuously for at least 30 days.

Not for use in cats with severe constipation.

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

Storage Instructions

Gut Rebuild does not need to be frozen or refrigerated, but US orders are shipped with a cold pack during the summer months as an added layer of protection from prolonged heat exposure. 

After delivery, store Gut Rebuild in a cool, dry place away from direct sunlight, heat sources, and excessive humidity. Routine refrigeration is unnecessary and can subject the probiotic to repeated temperature fluctuations during daily use.

The best-by date for Gut Rebuild is generally 4-6 months from the purchase date.

Frequently Asked Questions

It’s not hot where I live. Is it still necessary to ship with a cold pack?

Even if the climate at your location is more mild, higher temperatures may be encountered during shipping. During the warmer months, Gut Rebuild is shipped to all US destinations with a cold pack via Fedex 2-day shipping.

I’m outside the US. Will Gut Rebuild still be effective if it’s shipped without temperature-protective packaging?

Protective packaging is not a requirement for Gut Rebuild to be effective; it is simply an added layer of protection during transit. The probiotics in Gut Rebuild have been carefully studied and tested to ensure that they will still be potent and effective when you administer them to your pet.

Why does Gut Rebuild ship with a cold pack if it shouldn’t be refrigerated?

The cold pack is intended to help protect Gut Rebuild from extreme heat during transit, such as when the package is left in a mailbox or delivery vehicle in hot weather. Gut Rebuild does not need to be refrigerated for normal storage.

After delivery, store Gut Rebuild in a cool, dry place at room temperature. While temporary cooling during shipping can help prevent heat exposure, routine refrigeration is unnecessary and can subject the probiotic to repeated temperature fluctuations during daily use.
