If you're a big horror fan, you've likely noticed that before any other character notices something strange haunting their new house, their pets are acutely aware of what's going on.
But while most of us likely won't have to worry about our houses suddenly roaring "get out" in the middle of the night, there is a distinct possibility that the previous owners left behind something unusual or even creepy before we moved in.
And considering that cats and dogs often have keener senses of smell than we do, it is genuinely plausible for them to discover something's wrong with our homes before we have any idea.
So while one cat owner went to the lengths he did out of concern for his furry friend's well-being, he eventually discovered that the cat had his own reasons to be worried.
