I absolutely love this thread as I have to deal with what kind of litter I should buy that fits into my tiny budget.
First of all, when I first got Stanley we tried the pine pellets. He seemed fine with it and although it made the house smell ok, I found it was hard to scoop because the pellets didn't fall through the holes in my scoop! It didn't track too bad and clean up was a breeze (other than the scoop).
I find with the litter I am using now, it does smell more and tracks like crazy. Also, I am also scraping the bottom of the litter box all the time and it is clumping ON the scoop when I try to clean. What an annoyance! Also Stanley doesn't scratch anything and I find that he gets a lot of buildup on his claws from the clay clumping kitty litter.
I haven't tried the chicken feed yet. I can't remember if anyone said it tracked or not....
I use the arm and hammer odor eater thing for my kitty litter... I am not really sure if it makes a difference. Well, the one difference I have seen is that if I sprinkle a little on the bottom the waste doesn't stick to the bottom of the box. But after the first scoop it goes right back to the same problem.
Where would I fine the pellets? Just at any local Wal-Mart of pet store? What about the chicken feed? Do any stores sell it or would I have to go to an actual feed thing?
