More info on Eukanuba's Multistage renal (kidney) feline can food. The actual protein level is 7.9%, the fat level is 6.51% and the moisture is 74.9% (as is). The dry matter protein level is 32% and the fat level is 26%. This is the minimum recommended protein for ferrets and a higher fat level than most ferret and kitten foods. In addition it has a low phosphorus level, a high potassium citrate level, and a high level of Omega 3 fatty acid. No, it is not designed for ferrets, but until we have a ferret "kidney diet" this is a good option for older ferrets with chronic kidney failure. Hope that clears up some of the confusion, Jerry Murray, DVM [Posted in FML issue 3412]
