Just the other day I bought a 30lb bag of "GOOD MEWS" 'cat' litter pellets. But on the back it says that it produces no dust, etc etc.... and is safe for cats, dogs, all reptiles and small mammals. For about $8.
So I think it is an off-brand of Yesterday's News. Just recycled newspaper stuffs.
I hope I made the right and safest choice. *fingers crossed*
It looked like Yesterday's News to me, and the price was good. Still need to figure out how often the cages will need to be cleaned, with this new stuff. But safety was primary concern.
