It's a fascinating song, great concept and execution, both lyrically and melodically. Very enjoyable.

I'm going to agree on the litter box line, it's a creative line but too attention grabbing. I'd say right now you have a good cabaret song. If you wanted to boil the lyrics down and and make the melody more pop/hooky it could become a Burt Bacharach like pop song IMHO. I really loved the music especially the bridge and the last chorus. Congratulations, a wonderful collaboration.
