Automatic cat toilet, automatic toilet, automatic cat toilet Litter-Robot Open Air, Cat Robot Open Air dedicated guard fence. This is a guard fence specifically for the Cat Robot dome. By installing the guard fence at the entrance of the dome, you can reduce the sand attached to your cat's paws and the scattering of sand when entering and exiting the Cat Robot. Since I have disposed of the main unit, I'm offering this to someone who needs it. It has scratches from use. I believe this was a separately sold attachment. It has been washed and wiped with disinfectant wipes. ※Photos 5-7 are installation examples. Please note that this listing is only for the dedicated guard fence (photos 1-4), and the main unit is not included.
