I think the statement " Keep in mind that most carnivores aren't smart; they 
good reflexes. It's generally the omnivores that are smart." ...is a very 
one. I cannot accept that carnivores are subordinate to omnivore or herbivore 
intelligence and adaptivity. That makes no sense. It would appear it is 
enough to retrieve prey in a standard 3 to 1 predator/prey ratio environment, 
alone assume the predators are "dumb". The skill of ensnarling prey is far from 
simple, and when it is you against a herd, you have to be smarter than your 
Reflexes are given to carnivores for maneuverability, not to make up for
