stray neighborhood kitty

[legally blonde]

A few nights ago, I discovered a stray kitty (actually, my cats discovered this kitty b/c she was right under my window and Morty and Manilla went nuts). So, I put out a little bowl of cat food out for her, hoping that she would eat some. When I woke up the next day, the food was gone. I've been doing this for several days now.

I was thinking that I should try to catch this poor little kitty in a humane trap, only I'm not sure what I would do with her after that. I can't really keep her right now because I already have two kitties in a small studio apartment (although I'll probably be moving within the next six months to a bigger apartment). I'm not sure if there are any shelters in the area, but I don't know if I would feel okay about just giving her over to a stranger.

Does anyone have any suggestions about what I should do?
