Mountain Lion Scat tends to be segmented. The presence of hair, bones and teeth is common. Cat scat can be confused with dog scat, but cats more typically cover their droppings by scratching up ground materials. Mountain lion scat are broken cords or pellets with little or no tails.

Periodically scrapes or dung heaps can be found. These heaps are sites where urine & fecal matter has been left on a mound of earth and leaves or other forest ground cover.
Mountain lions frequently leave these near kills. ( To mark THEIR KILL! )
Male Mountain Lions appear to make scrapes as territorial markers around their kills and near trails and deposit urine and feces on them; these markers near KILLS, may be considerably larger than others, up to 2 feet long, 12 inches wide and 6 to 8 inches high in some cases.
An adult cat will usually defend a range of several square miles, marking its boundaries with "scent posts" - piles of dirt and twigs scraped together and urinated on.
Mountain Lion "scrapes" or "scratches", composed of mounds of soil, grass, leaves, or snow, are probably a means of communication with other Mountain Lions. These scrapes are generally 6 to 8 inches high and urine is deposited on the mounds.

by a male Mountain Lion near a kill.
This may be a territorial marker.

This appears to be a territorial activity along cougar travelways, particulary by males.
