Pea content in ZuPreem Grain-Free linked to bladder/kidney stones; peas later removed

The Holistic Ferret Forum documented that pea content in ZuPreem Grain-Free appeared connected to kidney and bladder stones, with several ferrets requiring surgery and reported deaths. A University of Tennessee veterinarian noted nearly all bladder-stone cases were in ferrets eating pea-protein diets, and controlled data showed legume-fed ferrets were 57.9x more likely to develop cystine stones. After community outcry, ZuPreem reformulated to remove peas.
