Just out of curiosity, is smelt a fish high in thiaminase? I once had a
shelter ferret, 3-yr old female, come in whose primary diet was little
frozen raw smelt! Ugh! She came with a half of a bag of frozen smelt, and
fortunately we were able to get her converted to a more suitable food
before the bag ran out. I was mostly concerned at the time because smelt
are very low in fat, but she was healthy and happy, with a quite nice soft
coat.
