The house where the cat lady lived was the home of an actual cat lady, although the films felines were provided by an animal trainer, Victor Salva had planned for a more extensive sequence inside the house but budget cuts forced him to trim the scene.
The Creeper:
She don't smell too good, Darius.
(at around 20 mins) After sliding down the pipe on his front side, Darry would not have landed on his back falling flatly as shown. He would have either landed on his chest, landed head first, or on his back rotating as he landed.
The Creeper's truck drives across the screen after the final credits roll -- he's still hungry and searching the back roads.
On the German Code 2-DVD (Platinum Edition) by MAWA/VCL (and perhaps the VHS as well) you can't hear the screaming of Darry/Justin Long when the Creepers tortures him. The screaming has been removed on the dubbed versions. But you can hear it softly if you tune in to the audio commentary by the director (who also comments the screams).
