I think using the song: “Rock the Casbah” by The Clash might
make for a fun ad for cat litter, with some slight word changes, like so:
“Kitties all like it, Rock the cat box, Rock the cat box (etc.).” And along
with the song, we’d see cute kitties entering and exiting the cat box. (But we
don’t need to see them doing their business.) Then the announcer chimes in,
saying: “Rock the cat box with the radical freshness of (whatever brand of) cat
litter!”
