Again you have dodged the problem of animals which simply cannot survive without meat. Shepherds can, but snakes and cats
and various other species cannot. And they cannot "adapt" to a vegetarian diet either, nor could they have adapted from it, without
major structural changes of the sort which would make them completely different animals.
Lock T-Rex and his wife in an ark for 12 months and only give them vegan...
it wouldn't be long before they busted down their stalls and went rampaging through the ark
eating anything and everything they liked...
before ya know it Noah would have a carnivore mutiny on his hands...
together with 3500 lb cave bears, 1100 lb lions and 1100 lb tigers, make for interesting hunger games.
then thrown in other things like ...
'Purussaurus brasilensis' ancient croc around 40ft long and 8 tons...
or even...
'Jaekelopterus rhenaniae', .. 8 foot giant scorpions.
