Before getting our cat we did a lot of research on different things that a cat needs and stuff like that, and one thing we thought was important was the cat litter. We knew that our cat would lick her paws which has been in cat litter and we didnt want her to ingest the chemicals from the clay based litter and we found Feline Pine. It is made from all natural ingrediants so she isnt licking the clay or dragging it all over my house. It clumps up pretty good too. It is flushable, havent had any problems with it clogging my toilet or anything like that. I like the fresh scent it has when you pour it in. If you clean it on a daily basis you wont have any smell either. I recommend this product to everyone with cats.
