Want to make one healthy and eco-friendly change to help you and your feline companion? If you have cats at home, it might be time to rethink the type of kitty litter you use to fill their tray. Conventional kitty litter is a combination of binders, with the main material being clay. The process of harvesting the clay is destructive to the planet, and the dust that's created is unhealthy for cat and human lungs. The good news is that many eco-friendly brands now exist that use old newspaper and wheat as an alternative that you can find wherever you buy your pet's food and supplies.
