I was just sent this video about horses that are used for carriage rides in New York City. Incidentally, I went by a horse show today and saw some horse rescue groups. Some of the horses were kept in such horrific conditions that they are now blind. One was tied to a stall for so long that even though it is no longer tied by its neck, apparently it doesn't know it. You can visit the Horse rescue group at Horsenet They also have a bunch of cats on the premises, almost all of which are already sterilised..
