[Highland Park] black and white kitten found - is it yours?

This morning, a tiny black and white kitten ran up onto my front porch as we were getting ready to leave. It's very tiny (maybe 10-12 weeks old?), very hungry, and very sweet. This is obviously a kitten who has been around people, but looks like it's been out at least all morning (i heard it crying for a few hours before it came up onto the porch) since it's pretty dirty and was scared. I think it might be female, though I can't really tell. We live on Hampton, between Mellon and N. St. Clair, and i doubt the kitten came from very far away. If it's yours, or you can give it a good home, please email me or call 412-361-6464. We got two cats already and really can't keep a third, adorable though it is! Genevieve
