Never again
After reading really good reviews, and having 3 cats, I thought this would be a good buy.
My cats don't like litter liners,not sure if this would make a difference to anyone else.
The litter when wet, acts like clay, and is so hard to clean from tray.
I didn't see much control on urine smell either. I had to do a full clean after 5 days, which is a real chore, having to soak in hot water for a good ten minutes before attempting to scrub and wipe clean. Back to sanicat non clumping.
