Bought this as a grain feeder for my horse, it worked, great that it attaches easily and is very sturdy, I didn't not evaluate the sizing too closely, if I had probably would not have purchased it. The muzzle of the horse made it so he really could only eat out of it from the side. I could see this working great for smaller animals (sheep, goats, chickens, etc) or animals will smaller mouths/heads :-)
