What is something that moves in a house not including people or pets
Insects like spiders, flys, and ants.
Doors. They open and close. Curtains. They move in the breeze of an open window. Windows. They open to let in the breeze and move the curtains. Time. No matter where you are, time passes. In a way that's kind of like moving.
vacuum cleaners - now they have these computer-vacuums that clean floors - they move by themselves
curtains, clocks, doors, fans, toys, etc.
