Can Clumping Cat Litter Dust Clog a Drain?

I have been using this clumping cat litter since I was asked to take in a 4th cat. I have 2 boxes, 4 cats, hoo-boy. I always put the clumps in a baggie and throw them in the garbage. But with the winter I noticed a couple of things. First, my vacuum was getting clogged with a super-fine dust. I have to clean the filter every time I vacuum.

Second, my voice had become very raspy. And finally, the sink where I clean the filter has begun to back up. So, I'm wondering if this dust is clogging the sink? In an earlier post you mention using mouthwash to clear it. Would that work with this dust?
