The Half Guard securely attaches to the bottom of the entrance of the Litter-Robot 3 with the provided clips so that even with vigorous pawing it stays in place. The Half Guard is 3.5″ as measured in the middle of the Guard. The sides are taller. FYI the Litter-Robot fence is about 2.5″ tall.
UPDATE! We’ve changed how our clips are made to make them stronger and more durable!
Clips for any Guard will only come in BLACK (regardless of what is pictured).
INSTALLATION NOTE: The two bottom clips use screws and nuts, which are included, to attach small stabilizer tabs on the inside of the LR. Just don’t completely tighten those until after they are in place on the LR. Installation video is now available in the photo gallery above!
My orange beast likes to periodically stop by the LR and dig a little litter out for good measure, since installing the Half Guard this has prevented him from getting any out, it’s quite entertaining for me to watch him try though! If you’ve got a real overachiever there is a Full Guard that is 5.75″ tall.
DESIGN NOTE: The original design for the Half Guard was graciously shared by jasonatepaint on Thingiverse.
