I think these are wonderful for someone who has allergies or who sensitive to dust or smells just because of the fact that it has very too little no dust and they absorb all the smell to the urine in the feces just like the other ones that I posted about and I believe that they don't irritate my allergies like others litters do and I would say definitely recommend and buy these it's great to have these because the kids can breathe easier I can breathe easier everyone else can breathe easier and plus it's good for the kitties
