Abby, would you be interested in selling a scoopfree tray?
And Gimble, I don't know what to tell you. I used a littermaid and an Omega Paws before this, both with clumping litter.
I think the "magic" is that it's a well designed, well done unit all the way around.
There is a nice long cycle that gives the crystals time to work.
I've never ever had any jams or clumping. Nothing sticks to any sides or drawers. I've never had to chisel anything out.
It's HUGE!! A bonus when your kitties are pleasantly plump.
And you chuck the mess. No emptying, no dragging a bag out to the trash. I like the cardboard because it's biodegradeable so I don't feel so guilty. I'm not sure what the tons of clumping cat litter I used to use does to the environment, but it can't be good.
So why am I asking Abby for a reusable tray?
Price.
I don't know if it would work as well as a litter sweep with crystals because I'm not familiar with the litter sweep. But from my litter maid experience, I think the ScoopFree has a better chance of being neat because it doesn't sweep up and into anything -- the flap raises. Did that make sense?
Anyway, I hope that helps.
