Your cat's journey to a healthy 2022 starts with improved gut health!

In a healthy cat, thousands of different microbes create a diverse and balanced gut microbiome. But when there aren’t enough beneficial microbes, or there are too many harmful ones, that gut microbiome stops working properly which can cause problems like diarrhea, gas, hairballs, or itchy skin.

Great knowing what is going on...

It is so great that we can now access knowing what is going on in the gut. Our special needs guy had a few issues and this helps us keep track of biotia. The only down side is you will love it so much you will want to do it for all of your furkids! <3

Chronic butt leaker no more

We ordered this as a last ditch effort for a cat that we had tried everything for. This did the trick! Thank goodness, he is now adoptable!

The test results with Alex was very beneficial.

The gut health test for our Mocha confirmed the imbalance of bacteria in his gut. It was simple to use and return for analysis. The personal review of the test results with Alex was very beneficial.

Third poop test on my cat

This will be the third time that I have done a poop test on my seven year old, raw fed, male cat. The first two test results gave me very helpful information on the condition of his gut, it was not in good conditon. He had rounds of poop pills after each of the those two poop tests,and his gut health had improved after each round. I am hoping that the results of this third poop test will give results at least as good as the results after the second poop test.

"I Trust and Rely On KittyBiome Testing"


I trust and rely on KittyBiome testing to give me the most complete picture of my patient’s gut flora good and bad. Their extensive library of bacterial behaviors and functions helps me to guide diet modification, exercise programs, and if formal gut restoration will be helpful. The KittyBiome testing really provides a piece of the puzzle for these difficult cases we otherwise would have neglected.

"I Consider KittyBiome an Invaluable Part of My Team"


With digestive issues being all too prevalent, I'm grateful to have access to healthy biomes that allow the restoration of my patients' gut flora and as a result their overall health. I honestly don't know what I would do if I couldn't test and treat in this way. With their passion for our animal friends' wellbeing and love of microbes and research I consider AnimalBiome an invaluable part of my team.

"KittyBiome Has Been a Wonderful Resource"


I have used KittyBiome's Gut Health Test analysis and Gut Retore FMT capsules with many patients over the last several years, and have seen remarkable improvements in canine and feline health over time, both in terms of food sensitivities and intolerances and skin conditions. The importance of a healthy microbiome is becoming more apparent every year, and AnimalBiome has been a wonderful resource. I highly recommend them.

The Science of Gut Health Testing

A Gut Health Test can tell you a lot about what’s going on in your cat’s digestive system and even how to correct certain problems. By identifying all the different kinds of bacteria in your cat’s gut, microbiome testing can determine whether those different bacterial populations are present in balanced amounts when compared to the gut bacteria of healthy cats. Those correct proportions are the key to a thriving, well-balanced microbiome.


Bacteria belonging to the genus Escherichia (a group that includes E. coli), for example, are beneficial members of the community when they make up less than 5% of a cat’s gut microbiome. But an overgrowth of Escherichia can cause diarrhea and other digestive issues. Bacteriophages (viruses that infect and kill certain strains of bacteria) that specifically target pathogenic strains of E. coli (such as PreforPro) can help to bring the digestive tract into better balance. The journal Antibiotics recently reported that such bacteriophages provide an effective alternative to antibiotic use in medical practice.


The Fusobacterium genus is also present in most healthy cats. When these bacteria are missing, digestion can suffer, but high levels of Fusobacterium are also associated with digestive issues, particularly diarrhea, so moderation is key. Bacteria in the Fusobacterium family do best in protein-rich environments, so if your cat’s KittyBiome Gut Health Test shows a deficiency in this kind of bacteria, increasing the protein content of their diet may help. If the test shows that Fusobacterium levels are high, the addition of a small amount of prebiotic fiber (like inulin or psyllium husk) to the diet can help bring these levels down by supporting bacteria in the gut that make molecules that help fight inflammation.
