Foxhaven, I agree...my mini has done wonderful on the Purina Miniature Horse and Pony. I do add a Purina vitamin and mineral supplement, because she doesn't seem to use the blocks. She loves it and it makes a good mash, when water is added to it. We end up putting in 3 cups of water, in each feeding, to add water into her, this winter. I put 2 cups super warm water in it, then stir, then once it is all breaking down, within seconds, I add another cup of cool water to make it luke warm. She loves it that way. And like you, I am very hesitant to change to something else, when this is working so well. I pay $16 for 50 lbs. here, so to me that is reasonable. Wish I could buy our dog food for that price! LOL
