“Was it organic soy litter vs former walnut shell litter that made less smell? I think it was big blue deep litter box I’ve had several years although cleaning w vinegar & soap before refilling. Cats adaption to soy helped with 1 Cup clean previous walnut shell litter. The Dome worth it, hardly any mess, again could be soy litter. Soy litter only 2 inches, I’m used to 3-4” (maybe that’s why walnut litter smelled more?). A full month only easily scooping daily & still no smell!”
“I added the dome because one of my cats likes to kick the litter out of the box. This is great at keeping litter inside the box and shielding any pee that is aimed higher than usual.”
