I've used Natusan for years and it's a great litter. They've discontinued it and I was advised to get Katkin.
Katkin is good with the smells but all urine sets in a thick paste like consistency which is hard to sift out. It sticks to the tray as well.
I have a hooded tray and I put the whole bag in so it's fairly deep.
Can anyone suggest similar to Natusan please as this really was the best I've used.
