Not a good product for us
I am only leaving a review as i based my purchase on reviews.
The tray is big, that's good.
Whoever put the carbon filters without a cover or something I hold them in has never had naughty kittens, they pull it off every day and chew the corners.
Also the lid doesn't fit well, I have to take it off to scoop the mess every time a
Any the flap doesn't swing freely, it gets stuck to the lip of the base, which either traps kitty in or out ( not sure which is best!)
So not great for us.
