Roughlugh 1.5 million tons of clay are mined annually just to make kitty litter for the nation’s 60 million felines. Much of the clay is strip mined, which destroys land and habitat, and some experts claim kitty litter accounts for more waste in landfills than disposable diapers. In addition, the silica dust in clay clumping litters may cause health problems in cats.
Fortunately there are nontoxic, biodegradable and renewable alternatives. Look for brands made from corn, wheat, nut shells, or recycled newspapers, including SwheatScoop, Feline Pine and World’s Best Cat Litter.
