This has simply made my life much easier as a home with cats. I usuly scoop our boxes 2-3 times as day as I have an elderly super picky cat. She will often follow me around meowing because she had used the box and I haven't scooped it and she needs to go again lol. This scoops after every use! With two cats I can't even begin to explain how much trouble this is saving me. And time! I havebt had any issues with litter or waste sticking in the tines of the rake. A litter refill tends to last me about a week or so but with two cats I feel that would be average. I'll never go back to traditional scooping again!
