Hi Danielle.  I copied your e-mail address wrong so I couldn't send this
directly to you.  I would think that if those litter crystals stick to
you when you're sweaty than they would also stick to a ferret's moist
nose (which could block it) or a wet ferret bum - which they could then
lick off.  I would think it's not good for them.

PS I use Swheat Scoop litter and love it.  But every now and then I get
paranoid about the dust.  If anyone using this has ever had a problem
with it and their ferrets please let me know!
