Our cat came back by himself almost 3 weeks after he was lost. We do not know what happened to him, but he seemed in good shape so we guess someone must've been feeding him and maybe looking after him. We do not know whether the LostMyKitty.com service contributed to his coming back. But we are satisfied with the service. We opted for automated calls to 2000 neighbors and most of the people we asked did get the call, although a couple did not, so it seems to be a good service though not perfect coverage. It was certainly comforting to know that so many calls went out very quickly.
