Uh-oh! I know that look!!!

OP I'm sorry to have to tell you this, but you have greebles in your house!

Yep, that there is the face of a cat seeing the horrors that the human mind is not smart enough to process. You got yourself a greebles infestation. Shadowy deamons that come for your soul, and haunt your walls.

Yep. No doubt about it.
