Hi Laurel; I'd think wheatgerm oil would be fine.. I sometimes also give flax seed oil, organic from the refrig. of the health food store. Both have the advantage of not having extra vit's D & E added so there's no danger of over doing an oil soluable vitamin. There probably would be loose stools if too much is given, but no harm done unless they miss the litter box:) take care, Gary & the gang of fur Timmy's web site=<http://www.concentric.net/~Gferret/>; He's the ferret totally healed from "terminal lymphoma" without drugs or surgery. :) ICQ#4461104 [Posted in FML issue 2467]
