Should I stay or should I go now (to get new curtains)?

Frightful shock whilst in deepest slumber. The cat launched herself from the bedhead onto my stomach then out of the room as fast and as hard as she could. Seconds later a prehistoric sound with simultaneous thump that felt like it rocked the house.

This morning my curtains are shredded and there are torn and shredded parts in the metal fly screen mesh. I don't know what the hell happened. Was it the mean cat from next door? Could a cat do that?
