Not recommend for clumping and wooden litter
An absolutely messy matter with clumping litter, the whole litter sticks to the grid and it is hardly to get away. For this cat toilet I need three times as long for cleaning than for a normal toilet.
Unfortunately this is also true for wooden litter, the humidity sticks to the grid and you have to shower with lots of water every time ;-( absolutely useless. Too low for larger cats, cat litter is scattered everywhere outside.
