Bests & Worsts Reviews from Amazon

These boxes are a home run!! I have 2 cats (a male and a female) that are just over 7 lbs each and I used to just have one large litter box. The male would not "bury" his poop and it was making me miserable :( He instead would make his burying motions on the sides of the box making lots of noise but not covering his mess... I replaced the big box with two of these boxes and the clouds parted and the angels sang!! Each cat actually favored their own box almost right away (as they do their sitting spots) and all issues have been resolved! I also find that they fling the litter a lot less after each visit. When they hop out they do track a small amount of litter that is caught by a scrap piece of carpet I placed underneath. No more walking on litter for me! NOTE: As to the reviews that state the top part of the box doesn't "snap" down, that is incorrect. If you are having this issue you have the box or the top part faced the WRONG way. The entry to the box that should be facing out has the squarish indented shape on the front of it and then of course the top part with the opening facing the front as well. They WILL snap together if you set them up properly. I have had ZERO issues with the grooves on the bottom of the pan (but do agree that that is a very poor design). I always keep about 4" of litter in the pan so maybe that's why. At the same time I purchased these I also switched the litter for the umpteenth time!!! I switched from World's Best to Ever Clean and all I can say is FINALLY!!!!! I have used every litter under the sun and this is the absolute miracle litter I have been searching for! Absolutely NO SMELL whatsoever... LOVE LOVE this stuff and it works great in these boxes! I also find that the litter is so adequate at clumping that the small scoopers and the bottom pan grooves are no problem whatsoever.... My cats are on the small side so these are perfect but I would probably hesitate to buy them if your cat(s) weighs more than about 9 lbs. You probably could but it would be very tight. These were such a lucky find and I couldn't be happier!
