Hello Tim, In response to your post regarding mucous in the ferrets stool, you have answered your own question! >The only change in his regimen has been that I took him off "Special Kitty" >that his owner was feeding and put him on Nutro's Adult Cat Food (32% >Protein). He also got into my cat's bowl of Science Diet W/D formula >(prescription for stomach problems), but he only ate a couple of teaspoons >of that. Any diet change can cause an adjustment irritation in the digestive tract, thus causing losses or mucousy stools. If the diet remains constant and the problem goes away - I would not worry about the changes. However if the diet remains constant and the stools seem irregular you may want to seek some veterinary advice. Happy ferreting, Alicia a shelter Mom [Posted in FML issue 2025]
