Lost super-friendly bob tailed cat (noe valley)

Bobo the cat has gone missing.
He roams the back yards of the 400 block of Alvarado (you probably know him already!), 900 Sanchez, 3700 22nd, 901 Noe.
Grey-brown medium-sized domestic short hair tabby, with a distinctive short curled-up bob tail.
He's extremely friendly, microchipped, not wearing a collar (he slips them), and certainly hungry and lonely.
He'll want to meet you! He'll want to come home.
He hasn't been seen since before that night of heavy rain, and I can only hope he took shelter in somebody's basement or storage space or garage from the back yard garden.
Please look! Or I could hope at this point that maybe somebody thought he was homeless and took him home and didn't know I was looking, and there'll be a happy ending to this story.
As if.
Best Cat Ever.
I still have keep looking for him, though I know that to be completely irrational.
