I've heard of Swheat Scoop; odor control isn't really necessary IMO, after using paper shavings for virtually all of my pets at one point or another, odor hardly bothers me anymore. Being dusty when poured shouldn't be an issue, I don't pour in fresh litter in the same room as the cats - just so long as it isn't dusty when stirred around, it should theoretically be fine.
Ick - if World's Best turns stuff yellow that's a no-go. With a 4 month old now, I'm completely not quick to clean up anything anymore, lol.
Feline Pine is pine pellets, isn't it? Just uniquely named. I used to use Equine Fresh for my small animals, and I loved it. I didn't think of using pellets as litter for cats, because I figured they'd want something soft to scratch around in, not hard and round.
Never heard of Dr. Elseys... according to their product finder it's only available at Petsmart near here, but I refuse to go there for any reason based on the condition of their animals every time I've gone there, and the seeming lack of care by the employees. Thanks for the suggestion, though, :/
