We tried one of the fancy auto scooping litter boxes once...
It was called a cat genie i think, but it was baaaad.

You hooked it up to the water line and it used these reusable/washable pellets.

It had a sensor that could tell when kitty was done using the litter box and then would start to clean it. First it sprayed water in the litter and rinsed all the pee away. Then it deployed a litter scoop to get any poo.
Then it would dry the litter with hot air.

Problem: if the poo was soft, sometimes not all the poo would get scooped out. Then when the litter was dried, so was the poo.

Do you know what smell you definitely don't want in your house?

Baked poo. Worst smell ever. 0/10 do not recommend! 🤣😑
