That unfortunately is true :( but this is one of the rare cases I'd have called the police and said "These kids don't know where their parent is. They have been missing for over an hour and apparently the mother is in another movie theatre. Could you get someone out here?" Don't bring up the fact that their moother is feeding them to death or that she abandoned them (especially with the kids standing right there) Just facts, but phrased in a friendlier way. And snap a photo of the cow when she waddled up, so there's some proof of who this egg donor is in case she was able to somehow get away before the cops showed up... When I was a kid and my grandma heard nobody was in the home, the cops came quick
