For any inquiring minds who have noticed my odd living room floor, as shown in this picture, the deal is thusly: When we bought our house, the carpets were made of sea grass. It is not allergy friendly and not animal friendly. After a while, we got sick of it and pulled it up. What you see is the bare concrete floor that was beneath it. Before we sell the house, we will put in new flooring, but we're waiting as to have new flooring that has not been animal-trod when we sell. While it isn't the prettiest thing, it's practical for us right now, and we're not going to live here much longer, so we deal.
