My vet told me that all the hairball remedy for cats and ferrets, etc.  is
basically the same, flavored Vaseline.  He suggested I just buy Vaseline
and give it to them daily.  If their poops are too Vaseline like reduce
the amount.  I give it to my guys at bedtime when they go into their cage
for the night.  That way no Vaseline poops outside the cage.
 
I hope that helps!
