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,
