Sure-Locked Homes is a 1928 Felix the Cat short produced by Pat Sullivan.
Plot[]
Felix, outdoors at nightfall, fears the unknown and runs home, which he watches closely throughout the night. The black cat wants to ward off the horrors he imagined on his way home. But inside the house, a series of black monsters resembling a gorilla, a bat, a huge spider and other strange characters follow his footsteps, following him in his escape to every corner of the house. The cat finds it impossible to escape from them or to imprison them.
Felix even uses the spider to try to grab one of the strange figures, but it escapes again and the black cat, in pure desperation, calls the police. Felix runs the wire himself to make sure that a police officer arrives instantly. Back at the house with the policeman, Felix tracks down the master of all these strange creatures and discovers that it is just a little boy practicing Chinese shadow casting with his hands in front of an oil lamp.
Shocked and embarrassed, Felix tries to disguise it as a joke, but the policeman, angered by the prank, throws the cat into stardom.
