I am unsure of what to do. I believe this kitten belongs to my neighbor across the street. A few days ago I heard a kitten cry. It was in a cage on their front lawn. They have gone away and left this poor sweetie. I saw kids playing with it at the park. Then yesterday I saw it jump off another neighbors balcony about a 15 foot leap. Then a stranger brought the kitten to me, and asked If I knew who it belonged too. I was shocked when I saw how small she is. You can feel every bone in her body. She is able to eat canned food with milk mixed in. She uses a litter box well. DH say I need to give the kitten back to them when they come home. I want to take it to the city and give it to the SPCA. DH says they will probably put her down.
She does have a fair chance of getting put down at the shelter. Have you tried to contact a no-kill rescue group? BTW, cow's milk isn't that great for kittens. Other milks are fine, though.
I think I have pushed him a little over the edge 
At least for now she is safe, warm, fed and happy
