I use Aubioise for all of mine. I have a small manure clamp so straw is not an option. It's super easy to clean and I only take the wet out once a week!
Hello Mrs. Jingle - you seem like a very educated, reasonable sort. I'm a little late to the party, but a contact sent me this thread. I am the buyer of the horse. I'd be happy to tell you my story but I don't know how to get directly in touch. (I'd prefer not to post publicly here.)
