“The dome only adds a little bit of height to the box and in my opinion, the litter box should just be this tall anyway. I put a plastic bin lid flat over the top of the dome to truly make it a full-covered dome. This helps with the dust and odor, and also shields me from having to see the poop inside (until my daughter does her nightly scooping). My cats have to squish down to make it work, but luckily, they are very agreeable!”
