yesterday's news is actually cheaper than most of the "specialty" sorts i've tried. i liked it but it doesn't clump so much as crumble when wet, so i found i was throwing out so much litter every time i scooped, and going through bags of it much faster than necessary.
i switched to world's best which is made of corn cob i believe, and is scoopable. it scoops just like a clay litter but is nontoxic and biodegradable, and though it's more expensive i go through less of it because of the clumping action.
but yeah i've heard mixed things about pine, that there's something in pine that is bad for cats and other animals, but i've also heard the feline pine litter is safe. i dunno if it's treated to remove whatever chemical causes the reactions or if it's made using a different part or combination of parts of the tree, or what, but i've heard it's safe. however a lot of people still don't believe clay is unsafe, so i would research it more before using it longterm
if you already bought it i'd say go ahead and use it and just watch for any skin reactions, and look into it further or switch brands when it's time to buy more
I'm singin' here to get rid of fear
Hope it disappears right here with the rain
But I know life is pain, not like a fairytale
Meaningless to pray, so just goin' on my way
