Nice! That is a good idea.

I personally have THIS electric litter box and LOVE IT.

I got it last year while it was on sale for $80. It was that price just a few weeks ago so I guess it varies (it's $100 with prime currently).

I had to replace the lower motor a few months ago because I didn't realize litter dust was getting into the gears and stripped them, but it was still under warranty and now I realize to check it now and then to clear that out.

Now my cat always has clean litter, and I can dump out the tray once a week. I even line multiple grocery bags in the tray so I can just pull out one and go. (and I also place dryer sheets between each bag to pretend it gives a bit of air-freshner magic, lol).

I've never used any other kind of electric litter box so I don't know how it compares to them, but this one is so simple in it's design. The round bowl part rotates very slowly 24/7, sifting any clumps to the conveyer belt part, which carries it to the dump tray.

You have to use the right kind of litter. Quick clumping litter doesn't provide strong enough clumps, they just kind of break apart on the upward conveyer belt. I personally buy a tub of litter from Sams and it works perfectly, keep the tub by the litter box and refill it as needed. Then when I run out of litter in the tub I consider that it's time to clean out the whole thing (3 months or so).

The thing they gave with to make a higher wall doesn't stay in place at all so I just leave it off. So if your cat is prone to kicking up a lot of litter it might not work well for you.

I had two 12lb cats using it regularly with no problems.

I just really love this thing so much, I tell everyone. No more scooping or sifting. So awesome.

Of course, my cat prefers to poop in a bed of pine needles in the yard, because he's a cat and can't appreciate nice things.
