YOU SAID:
I eat puppies and puppies eat kittens and kittens eat mice and mice eat cheese
INTO JAPANESE
私は子犬を食べ、子犬は子猫を食べ、子猫はネズミを食べ、ネズミはチーズを食べます
BACK INTO ENGLISH
I eat puppies, puppies eat kittens, kittens eat mice, mice eat cheese
INTO JAPANESE
私は子犬を食べます、子犬は子猫を食べます、子猫はネズミを食べます、ネズミはチーズを食べます
BACK INTO ENGLISH
I eat puppies, puppies eat kittens, kittens eat mice, mice eat cheese
That didn't even make that much sense in English.
