What is the name of House’s pet rat in House M.D.?

House’s pet rat in House M.D. is named Steve McQueen.

Steve McQueen is a small but memorable detail from Gregory House’s personal life. House keeps the rat as a pet, and the name references the American actor Steve McQueen, known for films including The Great Escape and Bullitt. The choice fits House’s habit of using unexpected cultural references and treating ordinary situations with dry humor.

The rat is not a medical case, a patient, or a member of House’s diagnostic team. Because House has several unusual possessions and hobbies, viewers may remember the animal without recalling its name. The name should also not be confused with the name of the actor himself: in the series, “Steve McQueen” is the rat’s name, borrowed from the celebrity’s name. This minor character detail illustrates how the show extended its characterization beyond hospital cases.
