My female cat is almost full sized and likes to climb the net curtains, which are ripped to shreds because she is so large. I want to replace the curtains, but not before I put a stop to this behaviour, which seems to happen when I am not in the room (unless "they just ripped themselves").
Most of my cats have been strays that have just shown up, but this one is a definite house cat. She came from another family just as she was maturing.
