Just an addendum. I know that a number of people know about biotin
deficiency from raw egg whites, but to learn about thiamine deficiency
from raw eggs as well just go to page 168 of _Biology and Diseases of
the Ferret, 2nd ed._. Too much of the wrong fish is a more common
cause, but raw egg also can do it per the second sentence in the first
paragraph on Thiamine deficiency. Aren't veterinary texts wonderful?

That is a divergence, though... The main subject is avoiding poisoning
incidents.
