Ringtails are nocturnal, cat-sized carnivores. They are good climbers and are found in habitats that range from dry canyons to wet woodlands, in highland and lowland terrain. They prey on small mammals, but their varied diet also includes other vertebrates, insects, nuts, and fruit. These animals are solitary and territorial, marking their home ranges by depositing urine and feces.
