Iris Ohyama Cat Litter Box with Scoop, Up to 7kg, Gray, Top Entry, Cat Litter Tray, Enclosed, for Kitten, High Sided, Hooded, Large, Jumbo, BPA Free, Deep, Easy to Clean, TECL-20

We have 5 cats and a dog who delights in collecting their little "presents". On top of that, kitty litter got everywhere, even with our litter catching mats. I finally had enough and started searching for solutions. I bought one of these to try it out.The cats had no trouble transitioning, the amount of litter tracking was significantly reduced, and the dog lost a free snack source. Success! I bought more to replace the rest of our standard boxes.Pros1. The cat entrance is larger than other top entry boxes I looked at. Much better for our two chubby kitties.Cons:1. Shipping cost. I could have picked up 5 high end self-cleaning litter boxes for less money after shipping was added to the price of these boxes. But I couldn't find a better option to address all my concerns in the space we have available.2. The included litter scoop. It's a clever idea to be able to hook a scoop on the litter box, but the scoop feels too dainty. Maybe it would feel more appropriate for the job with only one cat?3. I have had to experiment with alternative deodorizing methods, but I don't think the charcoal filter in standard litter boxes really does anything, anyway.
