I have a litter robot that I bought used and so far it's pretty nice, but I have 5 cats and would like to mod the drawer so I can put a bucket or something underneath so we don't have to empty it as often. I've seen a few videos about people nodding theirs, but I haven't found any actual instructions on how to do so. Mine doesn't connect to wifi or anything. Does anyone know what I actually need to do to make it so the waste can drop into a bigger container?

Also I'm missing the piece that connects the dome to the base in the back. Does anyone know how I can buy just that piece? I didn't see it listed on the website.

Thanks for any insight.
