My ferret recently had surgery due to stones in his bladder. My vet says the stones were caused by his diet, and he's seen this case before with other ferrets on the same diet. I have been feeding them ZuPreem grain free since I brought them home about a year ago. I am looking into a raw diet for them but there isn't much information online and my vet says it's not ideal as it is hard to give them the right amount of nutrients. He suggested a high quality cat food but everywhere i look online says to never feed ferrets cat food. I am not sure what to get them at this point... I like the idea of Wysong as it has been recommended many times on a lot of ferret sites but the only store in town that sells this brand only has the dog/cat foods. Would a cat version of Wysong work? Or any other diets you would highly recommend for my ferts?
