“I like the dome because my cat before using it got litter behind the box or beside the box and that doesn't happen when using the dome.But he does tend to knock the dome upward so I have to tape it on the sides.”
“The dome helped to keep my kitties business inside the box. We had some issues with the cats being close to too big for the large boxes and sometimes peeing over the edge due to the way they stand. The only negative I can say is that it took some figuring out how to assemble it but after a few minutes I figured it out.”
