Have a 17 yr old male cat that has seemed to have tummy issues most of his life. Had Giardia when I first got him. I think that messed up his system. We dealt with frequent vomiting and tried all kinds of things over the years. He had skin issues that the vet kept saying was fleas---NOT!-- I really wish I knew about this Animal Biome stuff 15 years ago! I had a second poop test done after 1 year, and his gut Biome has improved even more. He is a much happier fellow, very playful. The itching has basically stopped, no more drippy nose or vomiting up his food.--occasional hair but not balls--And his tummy sore spot is almost back to normal. His fur is filling back in. Got a Rx to help calm that spot down too. Highly recommend giving this system a try. We started out slow with dosing out of caution of vomiting and diarrhea. Any future pets we have, dog or cat will be getting this testing done out of precaution. Giving him the Daily digest and 8 in 1 mushroom blend as suggested.
