Poor Squeaky is getting so old and uncomfortable with her arthritis that I decided that we really needed to buy her a couple of memory foam dog beds to use. One in the living room, and one in the bedroom. That way she can sleep near us and be more comfortable while doing it. Unfortunately the durn cat has decided that he wanted to use them as supplemental kitty litter boxes, and after several attempts to clean them appropriately and prevent the cat from repeatedly soiling them, we determined that we needed to replace them with waterproof/weatherproof orthopedic dog beds.
Our hope was that the waterproof dog beds would be able to be washed off easily enough for the odor to be eliminated, but that was not to be. After a couple of weeks of constantly cleaning those dog beds, we ended up just putting them outside in the hope that the sun and the rain would deodorize them.
You may suggest that we “get rid of “ the cat, and although we did discuss that as an alternative solution, his advancing age was also something we had to consider.
