My 2nd ScoopFree electronic cat litter box in 3 years has now died on me. I am now in the market for another electronic cat litter box. Not sure if I want to get another ScoopFree since I think spending 0 in 3 years on electronic litter boxes is a little much and I also don’t have the 0 to spend. They seem to wear out quickly for just 2 cats. Wanted to see what has worked best for other cat lovers out there. Suggestions?
