It starts off explaining or talking about their selfishness and how people who tried to make pets of them eventually threw them out on the street. I think its a stray herd or maybe just one family that can't get water out of the faucet so they sit there for awhile crying about it.
I couldn't really make the next parts out too well but it looks like they got so dehydrated from just sitting there crying at the faucet that when it started to rain they were actually happy about it and some of them might have just stayed there and melted. Whether on not any actually get killed, the rain creates some muddy puddles they can drink from, albeit most likely very unhappily. A few more things happen that I can't make out then it kind of looks like some factory workers snag them all.
