Continuity mistake: The rocking chair that Lou is sleeping on is facing the side away from the doorway alongside the table next to it. When the delivery guy starts walking in to pick up the box and give the receipt to Lou sleeping, the chair and table are straight next to the doorway.

Continuity mistake: When the monkey's owners are having coffee and donuts at the train station, they notice that the monkeys are on the train. When they go out going after the train, they seem to be on a sidewalk next to the railroad tracks. But then in the next shot when the train fully has ran away, boards have appeared, basically to keep the owners safe from those tracks.

When they return home looking around the house for the kids, the bottle is gone and the carpet is completely clean.
