They're just so cryptic and secretive.

And so we've had to find these non-invasive methods they're often called to get information

about a mountain lion population.

The traps, which are about the size of a shoebox or even a coffee cup,

are attached to something that's along the animal's regular path,

like a tree that the puma has territorially scraped.
