The lion is just a big cat

The lion and the house cat belong to the same family, Felidae. Although the house cat and lion belong to the same family, they are different in so many ways. 

Lions belong to the category of felines referred to as big cats. Lions are the second-largest cat; tigers are the largest. They have long, well-muscled bodies, short legs, and enormous heads. A lion’s coat could vary from buff-yellow to silvery-grey or dark brown and orange-brown.
