I am under-educated in terms of chemistry hence the question and assumptions.
Basically, for our cats, we are using what seems to be the latest scientific achievement in litter sand - the litter crystals. Might be about 2 years now, since we switched from clumping sand to crystals.
As of late, I have started to pick up a somewhat toxic, disturbing smell, that feels to me as if those could be dust particles or something. Now, since I read that the litter contains something of silica family:
And also that the silica dust is somewhat toxic - this kind of matches, though, I may just be getting paranoid.
But yeah, when the cat rubs the litterbox after he has done his business, the smell picks up and it's heavily noticeable, really unpleasant for my and wifes nose.
Obviously, when the packages are being transported - the crystals rub/grind against each other, making them crumble and when I pour the crystals out - the crumbled parts get up in the air making the smell again.
Yeah, I'm starting to become a little concerned about the possible health hazards that the crystals could cause, therefore I'm looking for some clarification from you guys.
Are these things safe?
