    Thank you very much for the info! That’s the one I use for my cat and it’s great. Now I’m glad that it doesn’t have any heavy metals also!!

    Awesome! This is my brand too! After reading about the others you tested, I was beginning to worry bout my WBCL.
    And here it is, the day before I arrive at your site, you have tested it.

    Been worrying mostly about the dust, I find it on everything in the laundry room, where the box is.

    And wear a small dust mask anytime I clean or add or shake out the mats.

    Been coughing recently so wondered if it was the dust.

    FYI: The label says 99% dust free but it’s NOT. I scoop it very carefully so as not to raise more dust but it still gets on everything.
    Thanks for the testing!

      I have used this litter for years. It is the best of the choices. No Smell, least amount of dust and least amount of tracking. Expensive but I could breathe because the dust was minor. So glad it is lead free.

    I would love to see some more brands tested. I tried to switch my cat to this brand a year ago, and she wouldn’t use the box and instead started peeing on piles of clothing/fabric. I think she dislikes the way it feels under her feet. I had to go back to the one you already tested which came back positive for lead. It never even occurred to me that the dust would be tracked all over the house and furniture from her little paws!

    I was looking into this recently but I see a lot of bad reviews for bugs, corn moths, etc. I live in a tropical area and we already have a lot of bugs to deal with, I don’t want to risk having more.
    My kittens will eventually be outdoor cats but for now I need something. Thank you for testing it.
