I LOVE my Cat Genie and recommend it to everyone. I wonder if smaller slats would cause it to dump tons of granules. ?? I also would love it if the hand was made of slightly stronger material. Ours snapped in two places in 8 months. It still works okay, but I will be replacing the Genie hand. But perhaps a heavier Genie hand might put more strain on the motor. Overall, the Cat Genie is AWESOME. I don't think I would ever go back to the old, smelly, high maintenance litter box!
