Thay have another cat that lives there, and it is HUGE.
Fat.
Looks like a triangle when sitting.
It was on the edge of the porch, at the front of the open screen door. I thought it was a door stop, it looked like a caricature of a cat.
And then it moved when I walked by, very shocking.

Edit:
On reread, and review the date on that article, I realize that it was an old aricle. I'm pretty sure that was the cat I saw.
