Thanks for all of the advice!

The orange guy has gotten so friendly (when he wants something, anyway) - he is still so kittenish and hopefully Thursday is still early enough that he doesn't start spraying. He ran up purring this morning and let me really pet him, loved having the back of his head rubbed. Then he tried to suck on my finger. If all goes well I may let him out in a room in the house and see if he can't be tamed. He's "old" to tame, for a feral, but seems to be quite comfortable around me.

Last thing I need is another cat, but I don't see my living situation changing any time soon.
