I'm going to say that this is this is in front of the body case so Naegi can get his eye clawed out in front of a dead girl and god and everybody. The black cat doesn't initially move from its perch on top of the case, laying down with its front paws dangling over the front edge and its tail seen swishing back and forth behind it. It seems to be watching the light... you know what would be funny... if Komaeda shines the light at the glass and it reflects back into Naegi's eye.
