PetSafe ScoopFree Crystal Pro Self-Cleaning Cat Litter Box - Automatic Litter Box with Disposable Crystal Tray (Grey, Uncovered) - Ideal for Busy Pet Owners & Multi-Cat Homes

Have owned this product for nearly a year and you should buy it but here are some thoughts...I've had cats in my home since I was a baby. Now, at 40 years old, I still have never become good about scooping litter regularly. I'm a bit absent-minded, I'll admit that. So, this is a product that is made to help with my weakness as a cat owner and I am happy I spent money on it. It is very easy to set up and use. I bought a permanent tray and use my own cheap crystal litter instead of what they provide. And, it all makes for a great solution where the waste is being scooped under the lid regularly. My cat always has a clean litter box to go in and that's amazing.Now, there are still things to keep in mind if you are a loving but absent-minded cat owner like me! If you buy the Forever Litter tray then that will save money as you don't have to keep buying the PetSafe trays, but it does alter the experience with this so my issues may be unique to this setup.First, the poops get scooped into this tray at the back that is covered. But, if you get lazy about it because you don't see it, a lot of poop can still be piled up in that tray and attract flies. You gotta stay on top of cleaning that out every so often, which is trickier to do since it is covered so you don't see the waste. But, yes, every now and then, still do your scooping to make sure there's not a pile-up in there.Secondly, the grate that does the scooping can get crud on it and it's a little difficult to clean. No big deal but it's a new maintenance thing to do when you want to change litter.And there are a few other things but they may be unique to the litter I use from Walmart or other things. Overall, this has saved me a ton of time and has improved my cat's quality of life (cleaner litterboxes) so I am very pleased. There is still maintenance and work you have to do but it makes the entire litter process 90% easier on a cat owner and makes it 100% better overall.
