That's quite a bit more than your average walk-about!
On a related note (and not to take away from this cat's adventure), I've seen telemetry data on a female that went rim-to-rim (South to North) in the Grand Canyon in 4 hours (and there are limited crossings [i.e. 1 or 2 pedestrian bridges] of the Colorado River down in the canyon). For most people, a Rim-to-Rim is an all day hike.
