'The Cat Whisperer': Julie Klausner Cures Cat Hoarding For Martin Starr, Lizzy Caplan Of 'Party Down' (VIDEO)

As if Julie Klausner's Atom web series "The Cat Whisperer" wasn't funny enough, the show has featured such comic luminaries as James Urbaniak and Laraine Newman in past episodes.

In this latest video in Julie's ongoing adventures as the Cat Whisperer (tag line: "I whisper shit to cats"), she's joined by two stars of the dearly departed series "Party Down," Martin Starr ("Freaks and Geeks," "Knocked Up") and Lizzy Caplan ("True Blood," "Cloverfield"). Watch as Julie uses her mystical powers in this two-part episode to solve Starr's out of control cat hoarding problem.
