Description

The ringtail is black to dark brown in color with pale underparts. The animal has a pointed muzzle with long whiskers, similar to that of a fox (its Latin name means 'clever little fox') and its body resembles that of a cat. The ringtail's face resembles a mask as dark brown and black hair surround its eyes. Ringtail ZionFB edited

These animals are characterized by a long black and white "ringed" tail with 14–16 stripes, which is about the same length as its body. Ringtails are primarily nocturnal, with large eyes and upright ears that make it easier for them to navigate and forage in the dark. An adept climber, it uses its long tail for balance. The rings on its tail can also act as a distraction for predators. The white rings act as a target, so when the tail rather than the body is caught, the ringtail has a greater chance of escaping. The claws are short, straight, and semi-retractable, well-suited for climbing. Smaller than a house cat, it is one of the smallest extant procyonids (only the smallest in the olingo species group average smaller). Its body alone measures and its tail averages from its base. It typically weighs around . Bassariscus astutus 02 MWNH 367

provides balance for negotiating narrow ledges and limbs, even allowing individuals to reverse directions by performing a cartwheel. Ringtails also can ascend narrow passages by stemming (pressing all feet on one wall and their back against the other or pressing both right feet on one wall and both left feet on the other), and wider cracks or openings by ricocheting between the walls. As adults, these mammals lead solitary lives, generally coming together only to mate. A typical call is a very loud, plaintive bark. They produce a variety of sounds, including clicks and chatters reminiscent of raccoons. Ringtails have been reported to exhibit fecal marking behavior as a form of intraspecific communication to define territory boundaries or attract potential mates. It has been suggested that ringtails use feces as a way to mark territory. In 2003, a study in Mexico City found that ringtails tended to defecate in similar areas in a seemingly nonrandom pattern, mimicking that of other carnivores that utilized excretions to mark territories. Ringtails prefer a solitary existence but may share a den or be found mutually grooming one another. They exhibit limited interaction except during the breeding season, which occurs in the early spring. Ringtails can survive for long periods on water derived from food alone, and have urine which is more concentrated than any other mammal studied, an adaptation that allows for maximum water retention.

Reproduction

The cubs open their eyes after one month, and will hunt for themselves after four months. They reach sexual maturity at 10 months. The ringtail's lifespan in the wild is about seven years.

s opportunistically prey upon ringtails of all ages, though predominantly on younger, more vulnerable specimens. Also occasional prey to coatis, lynxes, and mountain lions, the ringtail is rather adept at avoiding predators. The ringtail's success in deterring potential predators is largely attributed to its ability to excrete musk when startled or threatened. The main predators of the ringtail are the great horned owl and the red-tailed hawk. Ringtails have occasionally been hunted for their pelts, but the fur is not especially valuable. Fur trapping has slowed down considerably, but current population sizes and growth rates remain unclear.

Tameability

Ringtail are said to be easily tamed / habituated to humans, and can make an affectionate pet and effective mouser. Miners and settlers once kept pet ringtails to keep their cabins free of vermin; hence, the common name of "miner's cat".
