Interesting note about how horses & cows eat :)

Cows have no upper front teeth, only a thick pad: they graze by wrapping their long tongues around grass and pulling on it. If the ground is wet, they will pull out the grass by the roots, preventing it from growing back. Horses have both upper and lower incisors and graze by "clipping the grass," similar to a lawn mower, allowing the grass to easily grow back.
