It sounds to me as though they really do not care if they initmately put forth any effort for the kitten or not! In that case I would definitely keep the kitten, unless they come looking for it. Then in that case, I would give it back to them. But many times, like was demonstrated by an older couple, at the Wichita, Ks. animal shelter, they rely did not want a cat. Namely, I am speaking of Sammy cat, my little orange male whom I rescued early last month. And besides, the fact that the kitten came to you would indicate to me that you are the one whom it wants to live with. Who knows what kind of home the original owners have for it. It is obviously not up to standard for a kitten's residence.
