I think, as long as the ferret is healthy, and working well it doesnt matter. I have an old friend who is in his 70s and has always fed slops. His ferrets are very healthy, and work amazingly. Although people say that feeding slops will cause dihorrea it is not always the case as these shits are fine. I feed mainly rabbit and mine havent had dry food since the summer, but now they will be on dry cat food in summer as the jameswellbeloved is far to expensive...
