Review on PetSafe ScoopFree Cat Litter Crystal Tray Refills – 6-Pack – 🐱 Non-Clumping, Low-Maintenance, Odor-Control – Choose from Original Blue, Lavender, or Sensitive Variants by Sandra Ford

I'm sorry. But I don't understand what all these people are complaining about! I have a cat that poops like an ADULT! lol We had three different trays and this one solved the problem.1. If cat poop sticks to the rake, set the timer for a longer time and let the poop dry! If cat urine leaks, put something underneath! or change bed linen a little more often! Or add crystal debris once a week!3. Put some trash deodorant in your storage area to get rid of the smell as much as possible. 4. I suggest you buy crystal fillers from the store instead of buying extra fillers. (the price is crazy) I had this product for 3 months and only had to change it ONCE. I'm cleaning out the vault so it's not cluttered with cat poop! and I add some crystal filler every week or two. My house smells great! And the tray is in the corner of my LIVING ROOM! (one bedroom) Great product - No odor - very little or NO maintenance -
