Sturdy but has some design flaws
My two cats have been using this for a few months now. It is well-made and a nice deep tray but there are some things which make it more difficult for me, whilst fine for the cats. Firstly the catches are very stiff and I have arthritis in my hands, so I have to ask someone else to do them for me when the tray needs a complete clean and refill. Fortunately the flap lifts up enough to allow more frequent removal of lumps. Recently, I have actually stopped using the catches which fasten the tray to the hood because of the inconvenience and have to carry the entire tray from the base instead of being able to use the handle. Secondly, unlike other covered trays I have had, the flap (perhaps because it is designed to lift up for cleaning?) does not fit tightly into the base of the tray so the smells are not so well retained inside. All in all, despite the relative strength and durability of this tray, I would probably not buy another like it.
