My cats did not seem to like this litter is had a strong although natural walnut smell and it was strong for me how much more so was it for the cats. I use two litter boxes for 4 cats. I cleaned out both boxes and filled one with LitterMaid 9lb Premium Walnut Clumping Litter and let it set in their usual spot available to them about 3 hours before I refilled the second box with their usual cat litter. I had one cat go to the box several time and she seemed disgusted with it because she would turn up her nose and not use it. It did get used during the night most likely by one of the other cats so I had a chance to scoop it and it seemed to hold up nicely enough. This did not have a perfume smell just smelled like walnuts but to me the smell was stronger than anticipated. My son and grandson did not notice it as much as I did. The smell did seem to dissipate by morning so it was not so bad. All in all it is not a bad litter but it is not the one we will continue to use.
