I know how expensive in buying and the exchange on the dollar is for me.
You can use olive oil and another good oil mixed together, with couple of
drops of vitaims for ferrets.  I do this all the time for mine and they
love it, much more reasonable.  Also you should make sure that the
ferretone can be imported into your country.  I know that in New Zealand,
it can't be imported.  I know from that info from Sam, she bought some to
take home from her visit here in Canada and when she got to New Zealand
Customs, they took it from her.
