Good l large litter box & price.
Spacious enough for 2 cat's to use & for very large cats to fit inside. Height quite good tall enough. Looks good & easy to clean. Opening big enough to put your hand holding the scoop inside & see in to remove wee wee litter & poo immediately without taking the whole top of the box off.
Faults are - that although there are 4 locks holding the top to the base & they work, you wouldn't be able to lift it up with litter in it - it would come apart, as other reviews stated (although i see no reason to do that as when I'm cleaning the box i take thd lid off & just carry the base over to the bin or the bin to the tray). The covered little tray is sturdy enough, but I wish it was rigid, thicker plastic.
The big issue is that the filter is unusable as cats/kittens can get to it to tear it to pieces - the carbon filter seems irresistible to them! It needs improved to have a covered filter - it smells fine though without - no problems with smells (until the flap is opened & you get a waft) ofcourse. Also - the flap is tinted dark black (not transparent) meaning the box is dark inside, the cat can't see in or out, & we can't see inside. This frightens kittens or beginners - but the door is easily removed until they're braver I suppose. - I had no problem with my young kitten though - I just poked her feather toy in the door & she couldn't resist going in after it, then when she went in I pulled the toy out, jingled it & she gingerly poked out a paw first, then out she came again! I'm pleased with the cat litter box, but would spend more money for a covered filter, a hinged opening front, & rigid material in future. I may even spend that ridiculous amount of money on1 of the dearest boxes, (which I'm sure they don't cost that amount to make) as it is worth it to have one that will not need replacing.
