Prednisone is very bitter, also in liquid form.  I had better luck with
the pedia version, prednisolone.  The vet needs to adjust the dosage
(since the pedia version is less potent), but I just have to put the
pedia pred in a little bit of ferretone and my ferret drinks it up on
her own.  Hope others have luck with this.
