Admittedly when I first got this litter tray, there were numerous reasons I didn't like it. The cardboard scratching post and dangling cardboard toys were just rubbish, I ended up binning those features. The carbon filter didn't stay in place and the cat kept taking it down, being a cat! I tried to superglue it on because I was so fed up of the smell coming through but it would nottt work so ultimately that got binned.. I have now found the best litter everrr (corn) and so this is no longer so much of an issue thankfully. Initially the putting together is fiddly too but you adjust as you do with anything. Pros: stylish, high quality rug for top area, cat does actually sleep on top of it and makes biscuits with the rug bless her, she's does use it and it's very easy to clean. I noticed people saying it's poor quality and weak plastic etc but I don't believe that. It's not the most deep litter tray but if that's such an issue then buy a deep heavy duty litter tray? I've had this nearly a year now maybe and it's not broke once or in lipped etc when carrying it. Those saying it's weak or the clips won't hold must be bare filling it deeeep with litter so it's super heavy or something but honestly I've had no issues! I hope my review is more helpful than those who left some, expecting miracles for this price range, really you get what you pay for. I would say this may not be suitable for larger cats as it is a bit low compared to most litter trays I've had. Thankfully not an issue for my cat.
