Classification of animals. All around the world many different types of animals are present. Many animals are quite similar to each other while others are different from others. So animals can be classified based on their similarities. The whole animal kingdom is divided into two main groups. They are Vertebrates and Invertebrates.
All three animals belong to the Order Carnivora. (Kingdom Animalia; Phylum Chordata; Class Mammalia, Order Carnivora) At this point they separate into different Families: Canidae for dogs, Felidae for cats, and Hyaenidae for Hyenas. After Family, there are two more separations: Genus and Species. Animals of the same Genus but different Species can sometimes interbreed, but it is very rare for two different Genuses to be able to do so.
