When it comes to taking care of cats at home, kitty litter is a necessity. But you should avoid the ubiquitous clay-based kitty litter, since unsustainable strip mining techniques are used to source and harvest the clay. Instead, look for alternative products that are flooding the market, like litters made from recycled newsprint and biodegradable materials like wheat, corn and soy. And, yes, there are ways to compost used kitty litter, but it’s a bit more complicated than traditional composting. If you’re interested, you can find those instructions online.
