What to do about a stray?

Crap. So just now as I was returning home from work I encountered a beautiful little stray cat on Bergen between Classon and Grand. He or she looks to be about six months old and isn't feral -- it was a bit cautious but came up to me when I talked to it a bit and rubbed its face against my hand.

The cat was mostly white with a few gold spots, slightly cross-eyed, with longish fur and a most magnificently fluffy tail. It didn't look terribly thin, but was fairly dirty. Anyone know of a missing cat that fits that description?

If I could have brought it home I would have, but I have a small apartment and two very territorial cats who don't like strangers and will raise holy hell if I try to close off any part of it to keep a stray quarantined.

From the looks of all the stickied posts on this board the rescue orgs are probably pretty overwhelmed right now. I'm not sure what to do to help this cat. Any suggestions?

The Slope Street Cats website offers a step-by-step list of what to do in that situation:
