How about picking your cat up and putting it on his cat bed..lol
The center should be farther forward to minimize reflections from the shelf. The might settle in back or on top although there appears to have something above it.I'd move the speaker forwards, build a platform above it and make the cat comfortable there.
Get rid of the cat.
Obvious solution.
I'd bet they could drive better than most humans too.Put some aluminum foil or double-sided tape where the cat wants to lie down. Another option would be to get a warm cat bed and/or a "cat tree" type of perch. A lot of cats like to be elevated, and they all like to be warm.
I'd rather have cats around than most humans.
