I don't know. I do recall the cats never getting near a bunny that had messy eyes. But Dad rarely brought those home. And mother would not consider feeding the family rabbit under any circumstances. You would have to be desperate to eat them when they were at that stage - very miserable looking things.
John I would not eat a rabbit that had a hint of mixo. Weepy eyes or drousy look - leave them alone I'd say. That's not an answer based on science - just personal preference. Milky does aren't on my eat list either, but they ought be safe to eat.
