Glad to report that I found two different foster places willing to take the kitten! So depending on who I hear back from when, she either goes to a foster group in brooklyn today, or one in manhattan on Sat.
She's gotten over her fear of humans - this morning she wanted her belly rubbed and to be picked up and cuddled so she should be totally adoptable. I was worried she might be feral, but luckily she's just young enough to still be socialized. She's very cute.
