I've given my horses squash, cucumber pumpkins, and whatnot in the past. Their favorite by far is watermelon, though. It's hilarious watching them eat it with the juice streaming out of their mouths, and their eyes half closed in pure bliss. You sure don't want to stand to close while their eating their goodies, my horses tend to be messy eaters, and they "share" by dribbling all over you.
Plain Old Dee, horses Dancer and Rain I believe in dragons, unicorns, good men and other mythical creatures!
