Query: Good idea but poor execution

The idea behind this product makes perfect sense. There's no reason we should be wasting our time picking through the litter box to remove the cat's leavings. Sifting the entire contents through some kind of screen like device to remove it all in one shot is obviously the way to go.Unfortunately this product was designed to be produced at the absolute minimum cost, and it shows. I'd be surprised if the 2 pieces of moulded plastic cost the manufacturer more than 30 to 40 cents when purchased in quantity. If it had been made with better materials than the thin plastic molded material it's made of, it could easily work a lot better.It's also far too small. I have three cats & use 2 of these units side by side, & they still aren't big enough to keep the litter from getting all over the floor where they're located.What a shame.
