Beyond what we’ve named on this list, other cats such as the American bobtail, Selkirk rex, Siamese cat and ragdoll cat are also considered large cat breeds. Both females and males across this breed are known to be intelligent cats that feature larger and longer features, large toe beans and a long history of origin. Many believe that these differences are a result of breeding, which would make sense for the more sophisticated Serval relative of the Savannah cat and similar breeds.
