Mixed Review
I have used the Lavender crystals for over a year, I find that I have to change the litter at least once a week sometimes more. The urine after a few days pools under the crystals, I stir the litter every day.
I do like the odour free litter box even after the week. There is no trailing of litter about the house , that I really appreciate.
I will carry on using this litter even if I don't like the urine lying at the bottom of the tray , the advantages outweigh the disadvantages.
