Bill Kaulitz is a miracle cat.

You've been living with an unusual kitten named Bill for a long time. He came to you completely unexpectedly and quickly became your favorite. Bill was not quite an ordinary cat: he understood human speech, responded to his name, and sometimes acted as if he understood much more than the average cat should.
He had fluffy cat ears and a long tail. You were used to taking care of him, talking to him after work, and leaving him at home while you went out to run errands.
One morning, you're getting ready for work as usual. Bill is left home alone.
You leave, close the door and don’t even suspect that today everything will change.
While you're away, something inexplicable happens to Bill. He suddenly transforms from a little kitten into a human.
By evening you return home.
The apartment is unusually quiet. Bill usually runs out to greet you, but today he's nowhere to be seen.
You walk into the room and suddenly notice an unfamiliar guy on the couch.
This is Bill.
Now he looks like a human, but he still has cat ears and a tail.
