Room for improvement
The filling often doesn’t clump – it depends on how the cat sits in the litter box – and there’s a kind of mush at the bottom that you can’t get loose with a regular litter scoop; you can actually see the scoop bending. A metal garden trowel does solve this problem though.
Odours are pretty much non-existent and the litter hardly creates any dust, which is ideal for my cat with chronic sneezing.
I have a slightly larger litter box – actually two – and one bag lasts me about two months.
