I took 3 of my ferrets in for a teeth cleaning today. One had a blood test in the beginning of January and the other two had their blood test today. When I went to pick them up the vet recommended that I start feeding them k/d diet (used for urinary and bladder infections) because some of their levels were off. I apologize for not knowing exactly what it was but I think it was C or Cr that was off and PH? I just don't remember but anyways it meant that there could be a potential for kidney problems. All three of these ferrets are approximately 2 years old and this shouldn't be a concern yet. He said that it is probably because of their diet being too high in protein. Now, I am not one to normally disagree with my vet but I had three other ferrets in last month for teeth cleaning and blood tests were okay and the one who had her blood test in Jan. was okay then also. I have not changed any food and so I am having a hard time believing that is the cause. Why these two young ferrets would have problems with the protein and my others- including a 7 and a 4 year old do not is something that I cannot understand. Does anyone know of something else that could be causing the levels to be off? I am very concerned that there is something else here being overlooked. By the way, I feed a large mix of foods with the protein levels between 32-38 but mostly around 35. Not as high as I have heard recommended. Is it just me or does something here just not seem right? Any and all ideas are welcome. Thanks, Michelle, Dave and the crew of 7 Tish, Dargo, Lexx, Cinny, Fingers, Chiana, and Lyekka [Posted in FML issue 3336]
