I am in a 2002 Mazda Miata. It is a two seat convertible with 5.2 cubic feet of trunk space. There is barely enough room for all my stuff. Let alone the cats stuff and then there has to be enough space to allow the cat to get comfortable. Nejm found a way.
The drive brought him anxiety, by mid day he was still looking for the right spot. In the afternoon he found it. He wedged himself in between the two seats on top of the center console and went to sleep. He wakes up and slumbers across the console to sit in my lap a few times. But would return to this spot for most of the ride.
