Still Not Cat-Proof.

 So we made the entrances to the hedgehog restaurant a little smaller... and no, it did not help at all. This is the hungry cat just about to enter the restaurant:

We had the camera set to take a photo every three seconds, but it is a little disagreeable and only shot every seven seconds. So obviously, we missed a lot, and that is the only frame where you can see more than the tip of the tail lying in the entrance. Not a single shot with a hedgehog either.

Which means there's two things on the task list now, one, to add some nice curved tunnel to the entrances, and two, to fiddle with the camera settings again...
