- It requires a big tray and normal shape (rectangular tray and same height lips);
- Environmental side, I remain doubtful ...
In the end, despite the simplicity of the system and because our cash cat has a very suitable form and that the bug is not complicated at all, we will maintain our usual litter, store brand: it combines the triple advantage of being less expensive, highly efficient and clumping (so really handy for cleaning). For us, there is no better.
That said, each cat his system! ;-)
