Noah's Ark - Mountain Lions

A mountain lion typically kills one deer a week, so a pair of them over a ten month span on the Ark would need about 87 deer-equivalents. Fortunately, the deer family has about 90 species, so taking just one of the seven from each species would do the trick. If you figure in lions, tigers, leopards, jaguars, cheetahs, snow leopards and clouded leopards, that would more than polish off all the deer. But no problem, could save the last pair of each deer species and let the big cats eat antelopes instead (there are 91 species of those). Oops, but there are also eight species of bears and 34 in the dog family (all of this just counting extant forms; presumably the extinct ones all died in the Deluge!). So those would consume the rest of the antelopes and in fact the rest of the ruminants (those in the "clean category", that came on board in sevens). This causes a problem for Noah, for after the Flood he has to sacrifice one each of the "clean" animals. If he is sure that the last female of each type is pregnant and sacrifices the male, there still won't be enough to go around, even if Noah's family is vegan (they would not be allowed to eat the "unclean" animals on board).
