Thanks to growler
I was recently introduced to Feline Fresh - it's a pine litter that comes in either pellet or scoopable form - it's a lot like sawdust, it clumps and is flushable..
It's also the same price as the clay stuff, which works well in my books!
Here's their website: http://www.planetwiseproducts.com/feline.htm
- they even have a rebate for a free first bag!
Thanks again growler for the tip!
