They are the earliest known resemblance of Wolves and Dogs that we know of today. The Miacis is often said to be a part of Carnivora,‭ ‬one of the main groups of carnivorous mammals that today include predators such as big cats,‭ ‬wolves and mustelids among others.‭ However, one reason why most of the species of Miacis are not fully included with the Carnivora is because they have forty-four teeth,‭ ‬whereas most modern members of the Carnivora have around thirty or even less teeth in a few cases. An adult miacis would grow up to be only about 20 to 30 centimeters long ( a maximum of 12 inches). This size allowed the Miacis to have a low slung body with well-developed fore quarters,‭ ‬particularly the shoulders and leg joints that would help the Miacis to climb up trees.‭ ‬As such Miacis is seen as an arboreal (arboreal - to do with trees) predator,‭ ‬which means that it hunted up in the tree canopy for animals like other small mammals and birds.‭ ‬The Miacis may have also raided nests,‬ eat eggs and chicks of birds, ‬and the still developing young of other arboreal mammals.
