Looking critically at the video https://youtu.be/_qG21K6XJRg
we get two different views of the sideboard door. From measurements of the opening between the two views the cupboard door is more open on the second view.
First view is when the alert occurs.
Second view is when CC is found.
Conclusion:
Cuddle cat had been placed in the sideboard cupboard between first view and second view.
You can really see it by the gap that develops as the bi-fold door opens Vertical gap very much more noticeable in the second photo.
Looking at your two photos above, Rob, which I am unable technically to reproduce, I notice that the camera position is different for each photo.
You may well be correct with your hypothesis, Rob, but with different camera positions it is unfortunately not possible to tell IMO. Move the camera a little and the view changes.
Some egg head like Alice might be able to work it out, but I am doubtful with no datum information to work from.
You have put such a lot of time and effort into working this out, I feel mean telling you.
But anyhow, IMO, Eddie alerted to the pile of folders on the counter and not CuddleCat at all. I wonder especially where the loose piece of paper on the very top of the pile came from. Did that have the smell of cooked pork on it? Bacon sarnies for breakfast? Eddie was trained on dead piglets.
Worse still had it been deliberately impregnated with the smell of cadavarine?
But who would do that?
