Not sure what pred you're using, but my ferret found the regular pred too
bitter. We had our vet do a prescription for pedia pred (prednisolone),
it's not as strong, so the prescription will call for a bit more to be
given. I put it in a tiny dish with a drop of ferretone and Mikette
licks it up on her own if I hold her. Some pharmacies will also compound
with flavors like raisin I think.
Hope this helps a bit.
Good luck
Risa
