I can understand why cats and dogs are smart since they don’t have to be on survival mode every day.
What I don’t understand is why are pigs smart? And why are sheep dumb if pigs are smart? They are in the same height in the hierarchy of needs.
In: Biology
Cats, dogs, and even pigs are carnivores. Pigs are more omnivores, they eat meat and plants. But sheep are herbivores, meaning they only eat plants.
In general, carnivores are smarter that herbivores. Carnivores need to hunt or they starve. My old biology teacher used to say, “It doesn’t take much brainpower to sneak up on a blade of grass”.
