Over the past five or so years, I haven't seen much for wildlife anywhere in the Tucson mountains, but this guy seems to be a pretty regular visitor to the ECDC trailhead in the early hours these days. I think that the squatter who lives in the parking lot may be feeding it, as the thing seems to have little fear and maybe even a fondness for human presence. I should also note that it responds to "here kitty, kitty".
