I can't say enough good things about the Litter Robot -- it's a godsend! We have five cats who use it almost exclusively. There's one regular box available to them, but they prefer the Litter Robot because the litter is
always fresh and clean, every time they step into it. And we think
that's why we're able to get by without the standard "one box per cat, plus one" rule! (I don't know where we'd
put all those boxes!)
Since the Litter Robot doesn't use a rake, there's nothing to get dirty or stuck... and although one of our cats weighs 19 pounds, nothing has ever been deposited that the machine couldn't handle.

It has been completely
trouble-free for us.
Our Litter Robot is a couple of years old now, and we're crazy about it -- but the new, improved version they're selling now is even better: the litter drawer is deeper, and is shaped on the bottom to make new deposits roll off to the sides, distributing themselves more evenly rather than piling up in the center. We hope to get one of the new ones soon, and then we'll move our old one into the bedroom for Abby, our former feral who prefers to live alone.
I'm not an easy sell at all -- in fact, having worked in advertising, I'm a pretty cynical consumer. But when it comes to the Litter Robot,
I'M A BELIEVER!
