I have a fifteen year old Andalusian cross gelding that has always been an easy keeper. My vet says that he could end up foundering if I don't get the weight off. Graffy finishes his hay in ten minutes and then has nothing until lunch time. I have tried everything and then I came across a slow feeder hay net article and decided to try one. Graffy now has hay until late afternoon and also has the bonus of chasing his net around the pen instead of parking in one place. I find he is happier and finally looking like he is on the road to slimming down. This is the easiest fix I have used and I want to share it with everyone. I found the N.A.G. Bags at slowfeeder.com. Good luck all. I will keep you posted on his progress!
