I watched this yesterday. It came just in time, because I was eyeballing those exact boxes on Amazon. I was so mortified I nearly cried. Coming home to (or even hearing) something like that happen because I wanted to save more time would have broken me. I would have never forgiven myself.

Edit: I ended up buying one that rotates sideways instead. Only reason I'm updating it is because someone in the video was like, "I believe in a cats self preservation to save them." My cat, who is afraid of heavy rain, runs to the litter box to watch, making it stop and start because she keeps poking her head in. She absolutely would have been caught. Even scaredy cats get curious.
