Cougar

From Wiki 24

A cougar is a predatory wildcat of a species found in the Americas.

[edit] Day 2

A cougar threatened the life of Kim Bauer for a time between 6-7pm, while she was lost the Angeles Crest National Forest and trapped in a snare. It departed on its own, and Kim was later freed from the snare by outdoorsman Lonnie McRae.

Lonnie later gave her a revolver which he said would scare away any cougars she might meet on the way back to the highway.
