Any animal that is not a ruminant. This includes pigs, horses and horse-related animals, all birds of any kind, all carnivores of any kind (wolves, dogs, cats, cougars, tigers, lions, etc. ), all omnivores of any kind (bears, raccoons, humans, monkeys, baboons, chimps, gorillas, wild boars, etc.) and all insects. Elephants, rhinos, hippos, and I believe giraffes don't chew cud either.
Neither do the little ground squirrels, rabbits or hares, moles, voles, mice, lemmings, shrews, bats, weasels, ferrets, pine martins, wolverines, skunks, lemurs, meerkats, rats, nor sloths Thus any animal that is not related to the deer family, goat family, sheep family, bovine/bison family, camel family and antelope family do not chew cud or, in essence, are not ruminants.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
