Yes, I see what you mean.
Is there any way you could remove things from your rooms, or make them inaccessible for her to jump on (I think I know the answer to this as I burble, but......) so that you could safely leave her while you're away from her? Perhaps in one room at least? I'm now trying to imagine how you possibly "cat proof" a room, especially from one such as her Faberlush Loveliness, and I admit it's probably unlikely, but I can see where your thoughts are, and I think you have a good point.
I do sometimes wonder if we shouldn't all just trust our cat's Judgment more than ours at times. Except for jumping, of course.
When Paddy was very ill after his last dental (when he was a young slip of a thing around 15) the first thing he wanted when we got him home, was to be out. Outside, with a capital O. I wasn't at all happy, but having witnessed first hand how badly things had gone, I decided to give him his head, although I admit I was pooping myself with anxiety, questioning the wisdom of my choice. I let him out and went with him into the garden. he wanted to be Out. I still hadn't grasped it.
He wanted OUT. Out on to the field with the wide open space, and the grass and the breeze, so - again incredibly reluctantly - I went outside with him, panicking in case he took off on his wobbly little feet as fast as he could go. He didn't. He threw up in the garden, wobbled out onto the grass, and I lay down beside him while he closed his eyes and just breathed. He slept for about an hour, in the open air, with me sitting guard, then he was happy to go back inside.
I couldn't recommend it for everything, but sometimes Ruth, you gotta go with your instinct and I suspect you have something there.
