Addendum (1/24/2017): NewtGingrich prefers mice and antelope:
”A lion is fully capable of capturing, killing, and eating a field mouse. But it turns out that the energy required to do so exceeds the caloric content of the mouse itself. So a lion that spent its day hunting and eating field mice would slowly starve to death. A lion can’t live on field mice. A lion needs antelope. Antelope are big animals. They take more speed and strength to capture and kill, and once killed, they provide a feast for the lion and her pride. ... So ask yourself at the end of the day, ‘Did I spend today chasing mice or hunting antelope?’”
