Hi Regina,
 
It is certainly possible that Amelia truly doesn't like Petromalt.  But my
experince is that sometimes ferrets claim not to like something (even
Ferretone in a couple of cases!), but when you smear whatever it is on the
roof of her mouth ("ugh, hey, get your smelly finger out of my.  .  ., ugh,
ooof!"), she'll lick it off and figure out that it's not so bad, and in
fact she was just kidding when she told you she didn't like it, and can she
please have some more now?
 
Anyway, it's worth a try or two.
 
Good Luck!
Dennis
