Fascinating. My process is strictly anti-cat. Not because I dislike the species, but, rather, because I find them to be very selfish with their part of the creativity, and they find subtle ways to cause havoc in my home if I revise their contributions even a little. So I've set up an electrical perimeter around my studio to keep them out of the process altogether. Still, they find ways in, mostly psychical ones, and with background noise that confuses my secretary.
