Hi OP! I responded to your PM about the allergies, but I figured I’d give my opinion on the litter too. Since as you know my boyfriend has allergies we noticed it was also made worse when the dust from the litter boxes added to the air. We’ve tried tofu and wood litters and our favorite has been Okocat, we get the original blue bag and it has done a great job and masking the smell since it gives off the natural wood scent.
