I have been feeding Blue Basics Limited Ingredient Fish and Potato for about the past month, based on my vet's recommendation. It does not have any of the ingredients that she told me to avoid. So far this food has worked out well for one of my cats, who was vomiting after eating, until I switched to this food. The problem is that I have found a lot of complaints about this food online, concerning cats who have developed UTIs, crystals, and kidney problems while on this food. However, I have yet to experience problems, my cat has stopped vomiting, and my vet still endorses the food, despite the concerns that I shared with her. I contacted Blue Buffalo about the online complaints. They responded that they were aware of the complaints on the Consumer Affairs site and that they could not control what was posted in an online forum. They went on to say that unless a "pet parent" contacted them directly they could not fully investigate the claims. They also told me at length about their process of selecting and testing ingredients. This does not make me feel better at all! I'm at a loss at what to do. I know that if you look hard enough online, you can find complaints about any food.. Am I overreacting? Should I trust my vet or listen to the online pet owners? Has anyone had a POSITIVE experience with feeding Blue Buffalo? I could really use some help deciding what to do. I'm afraid that switching food will make my cat sick again.
