How is a house cat related to a big cat?

Answer:
They really aren't directly related, as domestic cats and big cats are in different subfamily, but still fall under the family Felidae. Domestic cats are in the subfamily Felinae, whereas big cats (Lions, Tigers, Leopards and Jaguars) fall under the subfamily Pantherinae.
