I don't think it's random - it seems to detect your face and then place cats around it.
Well, on the picture i uploaded there are cats around everywhere of the picture now. If it is supposed to detect a face it is failing badly.
Almost like it puts cats on you
You can also tweak the subdomain to change the number of cats.
As the OP, MIND.....BLOWN
