I think my dad is seriously considering switching to Feline Pine or Yesterday News now. He didn't even realize you could buy something other than scoopable cat litter.
If you are not aware of this, you should be: They DO make cat box fillers out of products other than clay!
Scoopable cat litter is made from strip-mined clay and the dust from it can be harmful to people and pets. As my dad found out the heart-breaking and wallet-busting way, if your cat ingests the scoopable cat box filler, it can have disastorous consquences!
I personally use Feline Pine. It does work like the label says. It does a pretty good job of absorbing the smell. Just be prepared if you have more than one cat, to empty it more often than the reccommended two weeks. It is however, the same price or cheaper than the scoopable cat litter depending on where you buy it.
I have also tried Perfect Litter. This stuff is amazing and great if you have a cat that is prone to urinary issues, because it really does change colors if your cat is dehydrated or stressed giving you a heads up before it gets to the point of no return. (This happened to be what I had in the cat box when my kitty came home from spaying. The first day she was home it turned light pink. In a day or two it was back to normal color). It is however, a bit more expensive and you can only get it through the website.
I have also seen in the store, but not tried myself, Yesterday News made by Purina. It is made from recycled newspapers. It is the same or cheaper than clay-based scoopable litter as well.
I think one of the other great things about these products is they are made from renewable resources. In other words, they are more green than clay-based litter. So for the health of your pet (and the sake of your wallet), give them a shot!
