Bassariscus astutus

Ringtails (aka ringtail cats) are common throughout this range. They are primarily nocturnal. Sometimes you will see the reflection of their large eyes from your headlights They are excellent climbers and are able to move almost as fast scaling a rock cut as they can on the ground. They are quite common on rock cuts along the roads.
They are able to slip into amazingly narrow spaces. I have seen and adult ringtail enter a crevice which was less than three inches high.
They are about the size of a small fox, with a long tail which is about as long as the body. They are an active predator, taking small mammals, birds, lizards, snakes, amphibians and whatever else they can find, including the fruits of local plants.
