Unspeakable
What is going on inside of that tent and how long has that poor cat been stuck in it? From the looks of it it seems like that cat has seen things that we may never want to see for ourselves. The poor creature may need some kind of therapy for he has been through. I can only imagine how horrible it must have been.
The look in his eyes alone is enough to see that he will more than likely never be the same again. There are just some things that it is virtually impossible to unsee. My guess is that this unfortunate cat has seen a few of them. Just take it one day at a time.
