Here's the breakdown:
* Felidae Family: This is the large family that includes all cats, both big and small.
* Subfamily Felinae: This subfamily contains most of the smaller cats, including domestic cats and their wild relatives like the jungle cat and the sand cat.
* Subfamily Pantherinae: This subfamily contains the big cats, including lions, tigers, leopards, jaguars, and snow leopards.
Therefore, while they are all part of the same family, they are divided into different subfamilies based on their size, physical characteristics, and evolutionary history.
Interesting Fact: Domestic cats are actually descended from the African wildcat!
