Basic Trope: When something is thrown, crashes, falls, explodes, etc. the screech of a random offscreen cat is heard.
Straight: Somebody throws an object offscreen, and the sound of a cat's screech is heard, for no particular reason.
The cat screech happens near-constantly, even in places where cats could not survive, let alone plausibly be standing and getting hit.
Instead of a domestic cat, it's a Tiger, Lion or other member of the genus Panthera.
Downplayed: Someone is rummaging through drawers trying to find something, throwing clothing behind them. A cat previously following them lets out an annoyed screech from off screen.
Justified: This occurs in a place where there could very likely be a cat standing offscreen.
A cat is thrown offscreen and makes a very un-catlike noise upon impact.
The onscreen cat is hit with a random object from offscreen.
Subverted: Somebody throws an object offscreen in a series where this trope is frequently used. Dead silence follows.
Double Subverted: An object is thrown offscreen, and besides crashing sounds, nothing is heard... until a few seconds later, when the cat cries out.
Parodied: All the dogs in the area turn to look for the cat in question when this trope occurs, and end up thoroughly confused.
Zig Zagged: An object is thrown offscreen. A cat cries out. The hero, who has a soft spot for little kitties, looks dismayed...but the camera pans over to where you think the cat would have been, and there is no cat. It's then revealed that the object narrowly missed the cat, who is now up a tree. Later, the cat is seen throwing the object back at the person who threw it in the first place.
Averted: Objects go crash, get thrown, etc. and no screeching cats are heard.
