I'm using Feline Pine now as well and I really like it. The only negative side is that our kitten tries to get my attention by playing with the pellets, but other than that, it's been pretty good.
Since our new kitten came into the house, last November, we've used:Tidy Cats
-- Pretty standard stuff, but not very flushable and the clumping litters always worry me with young cats. Plenty of tracking and it would definitely smell after awhile. Yesterday's News
-- I liked the concept, but the kitten would play with it more than anything, and I didn't like the thought of her eating old newspapers if she had the inclination or felt playful.The World's Best Cat Litter
(corn) -- Clumped hard. I like that it was flushable and natural (non-toxic if she ate it), but she got it everywhere. I initially THOUGHT I liked it. Had to vaccuum almost every day because of tracking...half of the litter was in our vacuum before long. The smell was moderate -- bad if you let it go a few days with 3 cats and 2 boxes. A bunch of wheat-based litters
-- Similar to The World's Best Cat Litter. Some wheat litters are better than others. I also liked the fact that these were natural, but some of them didn't clump very hard and urine became like soggy cereal. Trying to clean it was like smearing mud. Granular Pine litter
-- Before getting Feline Pine, we tried a granular pine litter (small grains instead of large pellets, can't remember the brand name). This turned into sawdust pretty quick and got tracked everywhere within a few days.
The smell out of the box was nice, but it reminded me of something you'd use for ferrets -- not cats. Feline Pine
-- The difference between Feline Pine and the granular pine litter is that the litter comes in much bigger pellets. Therefore, the sawdust falls THROUGH the big pieces to the bottom of the pan (shaking helps). The cats then stand on top of the pellets, rather than on the sawdust. This makes a BIG difference in tracking. We have a litter mat and there's virtually no dust. Unlike clumping litters, poop often sits on top of the litter, so you want to clean the poop each day. I haven't noticed any urine smell after using it with (3) cats and two boxes. It's awkward to scoop because of the size of the pellets, but it doesn't take much effort to separate the pellets from the poop.
Our cats adjust pretty quick to new litter, but I realize that changing litters doesn't work for all cats. Feline Pine wins our award....
---- Very little tracking
---- Little or no smell
---- Not particularly expensive
