So, how long did the post-Flood/post departure from the Ark hibernation period for all the predators on the Ark last? They must have slept for years, otherwise predators, such as wolves, bears of all sorts, large cats like lions, tigers, jaguars, etc., avian predators, etc., etc. would have otherwise starved to death after being released from the Ark because there were only 2 of each prey animal like rodents, gazelles, antelopes, sheep, etc., etc., and eating one would kill the prey animal's lineage....and species. It would have taken years to build herds large enough to sustain being eaten occasionally/frequently.
And how long were the prey animals held in hibernation until the Earth recovered from the flood and all the vegetation re-established itself in quantities sufficient to support herds of grazing prey animals?
