In the sixth season episode Heeeeere's Lassie (airdate: March 7, 2012), there is a scene in which Shawn and Gus are in the coroner's lab discussing the latest victim, who was just revealed to have been drugged. Shawn asks the coroner, Woodrow "Woody" Strode (played by Kurt Fuller), to pull up the autopsy report for a previous victim he believes might be linked to the case.

Woody opens his half-closed laptop, revealing the website he was previously browsing, "Pleasureguide.net", specifically a page on furries with a series of photos of fursuiters and a login button labeled "Dare to cuddle?" A "Meow!" and various indistinct sound effects are heard from the laptop's speakers.

After hastily switching over to the window containing the autopsy report, Woody turns around and asks nervously, "Did you see that?" Simultaneously, Gus and Shawn answer "No" and "Yes" respectively.
