Makes my life easy
Used this nearly 4 yrs now, I used clumping litter Professional Classic Cats which works very well with it, I have tried 5 different ones.
I found at first the filter kept lifting but realised that part was not inserted correctly around the top edge.
Don't roll too fast, as you will get good litter in disposal tray. I empty before I go to bed every night and if you bang the bottom slightly all clumps fall off. If you do not filter regular the clumping litter will stick hard to the base.
I have the litter champ too so easy to dispose of and keep odour under control.
No more digging for nuggets! Yay and not so bad if someone comes in to look after cats if you are away.
