Cows are hard to kill. My mother is a veterinarian and a professor of hers once told this story: He was on a farm treating a cow for calcium deficiency (common for dairy cows), which is easy to treat, you just pump a bunch of nutrients directly into the cow and they'll go from being more or less incapacitated to healthy in a short span. So there he was, IV into the cow and hooks up the bottle to it and empties it into the cow while talking to farm. Finishes up and goes to disconnect the bottle from the IV, looks at it, turns to the farmer and says, "I think I just bought your cow." It wasn't calcium replacement, it was Lysol that he had just dumped a liter of into the cow!

The cow lived, barely seemed to notice.
