Bests & Worsts Reviews from Amazon

My two cats have been eating this for 3 weeks. My female Ragdoll came down with a terrible UTI. She couldn't urinate, and had blood coming out. I just got back from my vet's. He told me that Blue Buffalo was the worst food ever made, and that it was most certainly responsible for her UTI. He also told me to THROW IT OUT! He said not to donate it to a shelter, and that he wouldn't take it. I'm just reporting what happened to me. She loves it, BTW, but I now have to spend even more money on prescription food that my cat will have to be on for the rest of her life.
