My ferrets, too, are absolutely wild about Craisins.  Especially Boofer,
who has a sweet tooth.  I think it's important to limit them for special
occasions, though.  Check the contents, they're loaded with sugar.  In
fact, I just checked the package: they're over 75% sugar.
 
Boofer will still get her Craisins, just not very often.
