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. Capsules can be opened or given whole.

For 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. Foundational microbiome shifts take time!

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 is thoughtfully packaged to keep its probiotics safe and potent from our door to yours. Once the bottle is opened, store in a cool, dry place. Do not refrigerate or freeze.

The best-by date for Gut Rebuild is generally 5-6 months from the purchase date.

Great product

This really helped our 13 year old cat who has gallbladder concerns that led to killing off his gut “stuff”. He has been on it 60 days, eating well, no diarrhea and will see his specialist next week to see if he should stay on it or go back to gut maintain. One caveat is the current bottle caked. We live in southeast and house humidity is about 70% so we put new bottle in fridge.

Finally, constipation relief!

My poor tuxedo boy has had issues with constipation ever since starting medication for anxiety. I have been using vet prescribed medications to help with it, but they were never very dependable, and he disliked one of them. When the email for this came through my inbox, I jumped on it and ordered 3 months right away. I am very happy to say that after almost two months on this, and actually, since the first day I started giving it to him, he has been able to have a bowel movement twice a day. There have been a few exceptions where he didn't manage twice a day, but it is such an improvement! I open the capsules and mix it into his breakfast and dinner, and he seems to enjoy the taste. He is a happier boy, for sure!

My baby is finally happy!

When my kitten was 3 months old, she contracted cryptosporidium parasite and became extremely ill. For months she had severe diarrhea and dehydration needing constant vet visits and fluids. We had tried every medication and antibiotic available for her. After about 6 months of her being miserable, we discovered animal biome gut restore and gave it to her for several months. It helped a ton but not completely, and pilling her was no fun for anyone. When we got the option to be a part of gut rebuild study I jumped on it, desperate for any help. After the first month I noticed a huge difference in her stool consistency, it was better than it ever looked. I knew she wasn’t on the placebo because of the drastic change I’d seen. I was shocked when they mistakenly told me she wasn’t on the placebo. A week later they apologized for their error and confirmed she did receive the gut rebuild. I knew it because of how much better she’s been since giving it to her. She’s finally the happy little kitty that plays and loves again, I am so grateful!

Participated in clinical trial

William was a neonatal bottle baby I received as a foster when he was 3 days old. After he was weened and on solid food, his stools were always loose and very smelly. At 8 months of age, William had been on s. Boulardii FOS powder for his irregular stools. His stool consistency was normal on the s. Boulardii but still very smelly, since being on the Gut Rebuild, the smell has become less severe and he loves to eat the powder by itself. I would definitely recommend this product.

Much needed Product for after Antibiotic use

Finally a great product from a trusted business for replenishing the gut after antibiotic use which will destroy the healthy and needed bacteria to keep the gut healthy and working properly.

Frequently Asked Questions

How does Gut Rjebuild work?

Gut Rebuild contains three powerful ingredients that work synergistically to support a healthy gut microbiome for optimal digestion and overall health. The cat-specific probiotic Peptacetobacter hiranonis subsp. felis (“P. felis” for short) helps build a supportive environment for beneficial bacteria. S. boulardii provides fast-acting digestive relief. PreforPro® targets harmful bacteria to allow healthy microbes to flourish.

Which cats benefit most from Gut Rebuild?

Gut Rebuild is designed for cats with mild to moderate digestive issues. It can be especially beneficial for cats lacking P. felis, which is common in senior cats (9 years or older) as well as cats who have recently taken antibiotics like Flagyl (metronidazole) or Tylan (tylosin).

Why is P. felis so important?

P. felis is considered a keystone species in the feline gut, which means that it plays a critical role in maintaining a stable, healthy, and resilient microbiome. Even at low levels, it helps support an environment where other beneficial bacteria can grow and function properly.

Are there any risks associated with Gut Rebuild?

Gut Rebuild was specifically formulated to be safe and gentle for cats with sensitive digestion. However, in very rare cases, adverse reactions can occur. If your cat’s condition worsens after beginning Gut Rebuild, temporarily discontinue use and consider a slower reintroduction.

Can I continue my cat's other medications or supplements?

In general, medications and supplements can be continued while taking Gut Rebuild, with the exception of highly concentrated bacterial probiotics (e.g. Lactobacillus, Bifidobacterium, Enterococcus).

The yeast probiotic, S. boulardii, can be used with Gut Rebuild because it supports beneficial cat-specific bacteria. We always recommend speaking with your veterinarian before starting a new supplement.
