I looked into litter box robots and decided to try a low-tech solution first. I got an Arm & Hammer sifting litter box for under $20.
Basically, you dump the whole litter box into an equal sized sifter, then lift the sifter and give it a little shake, then dump the waste.
I can completely clean each litter box in 10-15 seconds. It’s not fully automatic, but I have no need for a robot anymore.
Speaking of palindromes, fun fact: “()()” is NOT a palindrome, but “())(” is.
The first one is like ABAB, the second is like ABBA.
