There is no reason to eat any specific type of food other than because you enjoy the taste and like Variety.
I mean I can have steak cut from a cow but that doesn't mean I won't enjoy Venison,Wild boar,Goat,Lamb,snake,buffalo,Ostrich Or even the taste of domesticated Animals such as dogs/cats.
That said the only reason I don't eat dogs and cats is because I have way to much respect for dogs and I consider Cats Vermin.
