Very important criteria: Animal product-free, e.g., no liver powder, with the exception of eggshell powder. I'm looking for a pre-mix that basically functions as a complete multi-vitamin and mineral supplement I can add to ground raw food for cats that are allergic to just about everything. Which is why it's important that the premix not have any organ meat in it. If this product doesn't exist, I'm game for suggestions for a multi-vitamin/mineral supplement I can add to raw ground that would make it a balanced meal. A million thanks in advance for any suggestions!
