My 4-year-old boy has seen two vets, an allergist, and a pet communicator. He has thrown up almost without fail after every meal his whole life, poor boy. We have tried multiple meds and various foods. Since we changed to this bowl he vomited only once this week, and that was a long, well-formed hairball, which is a huge improvement. I am beyond happy for my beautiful boy and hope we have a long-term solution.
