Love it! I specially love his fluffy ears and how he looks so serious!

Also, the way in which you described him makes it look like besides from being a Doctor he's also a detective of some sorts! Or sort of like a medium who can deal with super natural beings! That's just a really innovative concept and I like it a lot because you could give his stories a sort of light touch at first and then letting the readers fall into a spiral of intrigue as the story goes deeper and deeper into the lore of the Dr. and the cat city!
