They are messy, but easy to sweep up. Some have not been de-inked, and the inks used in newspapers can be quite toxic. They are generally formed into large, hard pellets that nonetheless get kicked out of the box readily and that, like all pellets, hurt underfoot. I find that this makes changing the cat box easier, rather than more difficult. The pellets in most of these products are far too large.
Peanuts are a highly sprayed crop.
Because the pellets disintegrate when wet, the box is easier to clean than if the pellets stayed hard. These litters tend to be in pellet or wood-flake form. I have some concerns about the safety of using anything with cedar oils in it. I have heard that cedar oils can be harmful to cats. Also, be aware that cedar oils will antidote homeopathic remedies.
