The Katz Motel is a small, no-vacancy inn located outside the town of Nowhere. Run by Katz, it follows strict anti-dog regulations, and contains, presumably, over 600 rooms and a vast underground complex. It appears solely in the Courage the Cowardly Dog series' premiere episode "A Night at the Katz Motel".
Tenants that stay at the motel have a tendency to disappear. This is because the service is part of an elaborate scheme on behalf of the manager to feed his massive collection of spiders. Rooms are rigged for surveillance and abduction, and contain easy access points for the insects to enter.
This equation has kept the Katz Motel running and Katz's pets fed, at least until the arrival of the Bagge family, who managed to escape with their lives.
His scam foiled, Katz has seemingly left the motel to pursue different projects.
