Ha! I had left my TV on, so by the light of it at 3am I rolled over and there was my cat, with a black smudge on his head.
Wait, he had been gone for 5 days. I looked again he was gone.
4 days later (9 days is a lot), someone says they may have him.
(They actually locked him up inside...he was 500 feet away! And would have come home!)
I asked if when they found him he had a black smudge on his head...
yup.
(From underneath a car.)
He never wondered far after that one!
They are so on the Astral plane, yes.
