Hey all, I just recently installed a new enclosed litterbox. It’s very nice and has a little plastic door that pushes in and out, but I dont think they understand these doors. For a long time they had an open litterbox but I wanted to get a closed one because my girl kept dragging things into the litterbox (ew!!) and they did have a pretty much closed litterbox when they were little kittens but it didnt have a door like this one.

Honestly they havent even been using it unless I guide them through the door and open it for them, and when they get in they havent quite figured out how to get out. How can I train them to push the door? Or do I need to just remove the door, thanks
