You start with a cat and an intact furniture.

Then the cat decides to destroy certain furniture.

You now have a few options.

First: admit defeat and offer the sacrifice to the cat.

Second: provide enough scratch alternatives nearby and make sure to get the cat everytime they start scratching the wrong thing to the scratch tree.

Thrid: throw the cat out of the room as soon it destroys furniture. (scratch tree outside of the room.)

Fourth: be an asshole and cut their claws like a monster that would cut fingers of children.
