None of the horses crap on the floor either. They are all stalled in absorbant bedding that is cleaned very frequetly. Have you ever been to a horse show before in the stall area. What about the germs you carry into your house onto the carpets? Do you not let your kids play on the carpets, what about the backyard? There is any number of places that you come into contact with germs. I guess my point is that I really don't see why there would be any more germs on these mats then you have in normal society. I guess my kids should probably be sanitized for caring for those same germy horses that is being talked about.
