If humans are in the same class as domestic cats we must also be in the same order true or false? explain?

False.





In the system of zoological classification, Class is higher level of categorization than Order.





Both cats and humans are in the Class Mammalia, meaning they are both tetrapod vertebrates that have hair or fur, and nourish their young with milk produced by mammary glands on the female. There are also other similarities, such as a single lower jaw bone (mandible), and three inner ear bones.





These traits separate them from other Classes of Vertebrata, such as amphibians, reptiles and birds.





After that, though, there are many different Orders of mammal.





Cats are in Order Carnivora, characterized by the possession of a pair of blade-like shearing teeth known as the carnassials, formed by the upper 4th premolar and lower 1st molar on each side.





Humans are in Order Primates, which also includes lemurs, tarsiers, monkeys and the other great apes.If humans are in the same class as domestic cats we must also be in the same order true or false? explain?
I think true, if an order goes before class..


i.e.





Order:


Class:





or something. So, if we are in the Mammalia order, so are cats. They give live birth, feed their offspring milk, and are relativly... not as far off as an alligator would be.
