Automatic Cat Litter Box Automatic Toilet Automatic Cat Toilet Litter-Robot Open Air Cat Robot Open Air dedicated silicone mat. This is a dedicated silicone mat to be installed on the step at the entrance of the Cat Robot dome. This is an optional part that can be replaced when your cat scratches or damages it, when dirt or odors cannot be removed, or when it has deteriorated after long use. Since I have disposed of the main unit, this is for those who need it. It has scratches and stains that cannot be completely removed due to use. It has been washed and wiped with disinfectant wipes. * The image in photo 6 is an installation example. Please note that this is only the dedicated silicone mat (photos 1-5), and the main unit is not included even if you purchase it.
