Diarrhea, Hairballs, Itchy Skin, or Gas?

Your Cat May Need A Gut Microbiome Health Test

Diarrhea, hairballs, itchy skin, and gas, are all symptoms of an imbalanced gut microbiome in cats. Since 2016 we have tested the gut microbiome of over 30,000 dogs and cats. The results have been surprising, with up to 80% of otherwise healthy pets showing some sign of imbalance1 and 1 in 7 cats showing unhealthy levels of E. coli in their gut microbiome2.

What Can I Learn About My Cat From Gut Microbiome Testing?

Microbiome testing provides useful insights that no other current veterinary test can offer. If your cat has digestive problems, diarrhea, hairballs, itchy skin, gas, bad breath, or immune system issues, those symptoms might be related to a gut microbiome imbalance.

Find out what’s going on inside your pet’s digestive system:

Your pet’s unique microbial community

Using DNA sequencing, we identify all the types of bacteria living in your pet’s gut, giving you a detailed picture of your cat’s or dog’s unique gut microbiome.


If important bacteria are missing, the gut microbiome is out of balance. Identifying imbalances early allows you to make changes to your pet’s diet or lifestyle that can improve or prevent symptoms.

Your pet’s diet

Each gut microbiome is unique. Different pets need different dietary adjustments to support the growth of specific beneficial bacteria. Food recommendations based on your pet’s individual results will help you make simple changes that can improve their gut health and overall wellness.

Missing bacteria

A comparison of your pet’s results with the healthy reference set reveals whether your pet is missing any important bacterial groups. The absence may be a result of antibiotic use, diet, illness, or other factors.

Harmful bacteria

Microbiome testing can quickly identify any problematic groups of gut bacteria. These may be pathogens that don’t belong in a healthy pet’s gut or normal members of the microbiome that have grown too numerous.

Here's What Our Customers Have To Say

Saved this little cat's life!

“When I tested with the KittyBiome Gut Health Test mid May 2022, it revealed a serious microbiome imbalance compared to healthy cats and a severe overgrowth of Escherichia Shigella (which is often seen in humans with alimentary lymphoma). I cannot express my gratitude enough as I truly believe that this product (Gut Health Test and GMP Gut Maintentance Plus) saved this little cat's life. ” - AJB., 5/17/2022

“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.” - Sheila B., 11/30/2020
