Prior to using Cat Biotic, I could not figure out what was going on with my cats. No matter what food they were on, or how many appointments they had, we still couldn’t figure out why they kept pooping blood. One day, while at work I looked into the Cat Biotic. After two days of usage, my cats no longer have stomach issues. I have now been using it for a few months, and I couldn’t be happier with the outcome! Thanks Cat Biotic, and Animart – Waunakee Pet Store, for having this product in stock! 😺
