Does anyone know of any actual scientific studies showing a clear relationship that peas cause bladder stones? When I mentioned it to my vet, he said he'd never heard of it and asked where I did. If there are any studies, please send me the IP addresses so that I can forward them to him. Though I do not use Zupreem, I am using 2 high quality cat foods (Origen & Wellness Core) that do contain peas though they are far down on the list of ingredients. I mix these 2 with Wysong Epigen 90, and my girl who had very seedy poop has been doing much better on a grain-free diet. Thanks for any info. Shron [Posted in FML 7961]
