The ringtail, known scientifically as Bassariscus astutus, is a small mammal in the raccoon family.

It is a specialist of arid, rocky regions throughout North America. While it is often called a "ring-tailed cat" or "cacomistle," it is only distantly related to true cats. It is the state mammal of Arizona and is widely distributed across many different desert environments. Globally, the species is listed as Least Concern on the IUCN Red List. However, it receives special protection in certain areas, such as being a Conservation Strategy Species in Oregon and fully protected in California.

Physically, the ringtail is built for life in difficult, vertical terrain. Its fur is black or dark brown with pale underparts, and its face features a dark mask around the eyes.

Its most striking feature is a long tail with 14 to 16 black and white rings. This tail is roughly the same length as its body and serves several vital purposes. It provides balance while the animal negotiates narrow ledges or limbs. The white rings can even act as a distraction for predators. If a predator catches the tail instead of the body, the ringtail has a better chance of escaping.

Movement is a highly specialized skill for this agile climber. The ringtail possesses short, straight, semi-retractable claws that are ideal for gripping surfaces. Its ankle joints are exceptionally flexible and can rotate 180 degrees. This rotation allows the animal to climb down walls with ease. To move through narrow passages, ringtails use a technique called stemming. This involves pressing their feet against one wall and their back against another to wedge themselves through. They can also move through wider cracks by ricocheting between the walls. In some cases, they can even reverse direction by performing a cartwheel.

Ringtails are primarily nocturnal animals, meaning they are most active during the night. They have large eyes and upright ears to help them navigate and forage in the darkness.

Most adults lead solitary lives and only come together during the breeding season in early spring. They communicate using various sounds, including clicks, chatters, and loud, plaintive barks. They also use fecal marking to define territory boundaries or attract mates. A study in Mexico City showed that ringtails deposit feces in nonrandom patterns to mark their space. This behavior is similar to many other types of carnivores.

Survival in dry climates requires unique biological adaptations. The ringtail can survive for long periods using only the water it gets from its food. Their urine is more concentrated than that of any other mammal studied, which helps them retain as much water as possible. Their diet is omnivorous, meaning they eat both plants and animals. In the winter, they focus on small vertebrates like birds, rats, mice, and rabbits. During the spring and summer, they shift toward eating more insects and fruit. Research on Isla San José showed that their diet changes based on what is most abundant each season.

Reproduction follows a specific seasonal cycle. After mating in the spring, the female undergoes a gestation period of 45 to 50 days. During this time, the male helps by procuring food for her. A typical litter consists of 2 to 4 kits. These young cubs open their eyes after one month and begin hunting for themselves after four months. They reach sexual maturity at 10 months of age. In the wild, a ringtail can expect to live for about seven years.

Despite their small size, ringtails face many natural threats. Predators such as great horned owls, red-tailed hawks, coyotes, and bobcats hunt them. To defend themselves, ringtails can excrete a scent called musk when they feel threatened or startled. This chemical defense helps them avoid being caught. Historically, humans have also interacted with them. They were sometimes hunted for their fur, though it is not considered very valuable. Because they are good at catching vermin, settlers once kept them as pets, leading to the nickname "miner's cat."
