My cat has FIV, heart murmur, kidney disease, and IBD. He was losing weight, had itchy skin, dirty ears, weepy eye, loose stool, and vomiting. He was on a hydrolyzed diet for years prior to this, thinking it was a food allergy, and this helped somewhat, but when he seemed more uncomfortable I knew I needed to keep searching for the problem.
I used their fecal test and submitted two samples to Animal Biome for testing, before and after using the Animal Biome products. The first showed my cat had an overabundance of bad bacteria (e coli) and very little diversity of good bacteria (2 types took up 80%). After 30 pills of Gut Maintain (to try to get rid of the bad bacteria), and 90 pills of Gut Restore (as well as a diet change to single protein food, and budesonide recommended by my new vet) I retested. His results showed no bad bacteria, and an improvement in diversity of good bacteria. His gut is still considered imbalanced, and they recommend more sporadic use of Gut Restore to keep him on the right track. I've chosen to do 2 pills a week, but may increase that with my next order.
Because I changed several things at once (fecal pills, diet, and steroid use) it is hard to credit Animal Biome products alone, but regardless his itchy skin and dirty ears cleared up soon after I began the Gut Restore. He still has occasional blood in his stool, slightly soft stool, and vomiting, but he has gained about a pound since beginning all these treatments (12.5 to 13.5). With his many conditions he's an extra special challenge, but I think Animal Biome has helped.
