I loved my small hole hay net, until I hated it. It slowed my Cushings affected Arab way down, helped him to relax and mellow out, allowed him to have hay in front of him all the time, and cut hay wastage down by at least a third. Then, after months of using it, he got wrapped up in it and strangled... he was still warm when I got went down to the barn for the evening feed.
My fault. I hung it up in accordance to the directions, but I hung it on a closed stall door, and my horse would stand in the open stall next to it and reach over to eat. He slipped his head in between the bag and the door, and got caught. But it made his life so much more enjoyable, that I am working on ways to use one for Ahab, but make it wicked safe. I have about five designs worked up so far.
