At my old stable in CA, our barns had stall mats to make the stalls more comfortable for the horses, both shock absorbent and warm in the winter.. They spent a lot of money and time getting the perfect mats for optimum leg health, etc of the horses.
At my stable here in NE, they say the mats are ONLY to protect the ground in the horse's stall against pawing, etc. I got a little confused, maybe a little agitated when the BO re-did all the stalls last fall because he replaced the stall mats with new mats. These mats are actually 4 X 4 square scrap from the manufacture of car belts (fan belt, alternator belt, etc). They are a little slick but he says he's going to put a membrane on them to make them less slippery. I asked about the padding and the effects on the horses and that's when he said that the only reason to have stall mats in a stall is to protect the ground, they have nothing to do with making a horse comfortable or protect against shock and standing.
So now I'm confused and wondering if I should be worried???
