Why Pet Flora? It is a unique formualtion of 29 active strains. It will slowly remove fecal plaque, in the process exposing pathogens which can cause brief bouts of diarrhea. But to the point of why- 80% of the immune system is located in the GI tract AND according to The Royal Society of Medicine Great Britian 90% of all chronic disease is caused by an unhealthy intestinal system. Clearly restoring (and maintaining optimal GI balance) is critical to resolvng any health issue.
Just keep in mind that we don't get sick overnite, and most likely we won't get better overnite either.
