I don’t know what Mingo is doing here. He was desperately trying to climb up that closet door, and was staring at a spot near the ceiling, but there was nothing there, not even a bug.
Whatever it was, it kept him busy for quite a long time, and it was pretty noisy, too.
This is screaming for LOLCat captions.
Apparently this is a typical orange cat ritual. Tater Tot has been doing the exact same thing recently.
