we changed to this size when our cat turned 1. No issue with the bottom of it. I read some people find it difficult to scrape clipped litter from the dimples on corners. They are not deep and we have not found a problem with cleaning it. Definitely would recommend.
This was disappointing: the curved corners made it difficult to remove clumps and there are indentations in the base in all four corners which get clogged up. Both my cats like to stand on the edge of the box when producing solids and the sides are too high and the plastic too flimsy to take their weight, resulting in worry that they will actually tip the tray over !
So practical, low enough for my kitten to climb into, used it when he was between 9 and 19 weeks. No spillage even though the little runt liked to dig his heart out. Good value as always, Zooplus
Nice large trays for medium sized cats and plenty of depth.
Trays feel a little flimsy, while rims don't seem to fit properly and one corner always seems to pop out. Maybe there's a knack to putting them on that I haven't discovered yet...
For the price though, I can't complain too much.
Very pleased with this item. The depth along with the protective edge are perfect at stopping the litter going everywhere (my boy is one that likes to 'dig to China'!!) Oh and the edge/rim is easy to attach/detach and good at holding tray liners in place.
