Why do cows have hooves instead of feet?

Because they lactose!

Did You Know?

"Lactose" sounds like "lack toes" — so cows have hooves because they lactose (lack toes)! In reality, cow hooves are made of keratin, the same protein that forms human fingernails. A cow's hoof is actually a modified toenail that can support over 1,000 pounds of weight!
