Hi Mike -- Glad to hear the LR is working out for you.
I have detected an odor about the LRII -- and, whether an odor develops could depend upon which cat is doing the pooping/urinating, what the poop is like (hard, soft, etc.), where the poop/urine is deposited inside the globe (in the litter or on other parts of the globe) and what litter is being used.
My cat has soft poop -- he poops near the door and will often hit an area not covered by litter. The uncovered poop can smear inside the globe when it rotates. The interior of the globe can develop an odor. I have not been using perfumed litters and the interior began to smell like poop at my house (the cats are using another box with crystals for urinating) despite my cleaning.
Also little bits of poop (depending on the litter, perhaps) can get dispersed with the litter under the screen.
I used Nature's Miracle litter when I was hand-scooping -- mixed it with two other flushable litters but this did not work well in the LR. However, someone just posted trying Nature's Miracle by itself in the LR and reported good results. So I bought a bag this weekend, scrubbed out the LR, and am giving it a try to determine if it controls the odor inside the globe.
Also, other forum members have reported that cats who like to dig apparently can claw through the rubbery black surface of the globe or have been able to in the past.
