I am searching for cat food and looking at reviews/videos. Most direct me to Acana and Orijen. Now looking at the reviews at Amazon both brands have complaints about causing kidney and bladder issues which is different than the complaints for other brands. I checked other brands like royal canin and Purina where the customers only complain about vomiting and maybe diarrhea which are common complaints about for any food. When i see comments like these, i always think about how many more people had the same problem but didn't think its the food or how many didn't bother complaining on internet. Are these brands Acana/orijen really good or just marketing success? https://www.amazon.com/LB-ACANA-Appalachian-Ranch-Cat/product-reviews/B01DJFXF68/ref=cm_cr_unknown?filterByStar=one_star&pageNumber=1 https://www.amazon.com/Orijen-Dry-Cat-Kitten-Food/product-reviews/B01I3IBQG2/ref=cm_cr_unknown?reviewerType=all_reviews&filterByStar=one_star&pageNumber=1
