NEVER eat a diseased cow, unless you know for certainthat the disease that the cow has will not affect the meat and ultimately you. But if you don't know, don't eat it, otherwise you could get very sick and die.

You've got to be kidding? How could a little ferret ever injure or eat a cow? Maybe cooked cow would be eaten by a ferret, sometimes I share my hamburger with him!

I DID turn into a cow once. She left a big ol' dent in the fender of my pickup-truck. Seriously, you don't become the thing you eat. Even if you could eat a whole cow--several hundred pound of beef--you wouldn't become a cow anymore than you become a deep fried pastry when you have breakfast at a doughnut shop.
No.

No, a cow will not eat meat, although there will be some curious cow that would probably try it, cows do not and will not eat meat.
