The cat, black with white markings, apparently became stuck on top of the cactus in a desert area near Saguaro Lake, KNVX-TV, Phoenix, reported Friday.
A witness said he first saw the cat there three days before it came down.
Slowly but surely, the cat started to climb down Friday, starting face-first before turning around and backing its way down. Near the bottom, it leaped off the cactus, making a safe landing.
The feline was seen wandering in the area after news crews left the scene.
