Automatic Litterbox Central

Do you think Wally-world (aka Walmart) will ever start selling those cartridges? I live in very rural town and pretty much WM or online are our only shopping choices. I was considering a Forever tray and then buying Tidy Cat crystrals, which are indeed available at our Walmart, but being in a wheelchair as I am now, changing the litter via the cartridge way is extremely convenient. I'm not sure if the Forever tray way is as easy to change, is it? If I could get the cartridges at Walmart though, I'd buy them in an instant.... in bulk too. I just love this Scoopree litterbox... it's absolute genius.... Kudos to the inventors!

I see that you don't go there personally because you are unable to walk. Anyway, there is a manual for installing the tray. You can read it so that you can easily install the new tray.
