Live food...why? Honestly & with facts!

Cooking also destroys thiamine, so those who feed fresh but cooked food to their cats (and presumeably, ferrets) should add a thiamine supplement to it after cooking.
Thiamine is added to commercial cat foods.
Some fresh fish is also off limits, as is frozen fish, due to the thiaminase content (enzyme that destroys thiamine).

I totally agree with you. That's exactly how ferrets get a thiamine deficiency. From fish meal in low quality kibble. I hear eggs do the same.

Good thing I feed live!
