Biodegradable litter is an excellent alternative to the harmful dust clouds, harsh chemicals, and potent perfumes that are commonplace in many clay-based litters. Typically these biodegradable alternatives are made from, wood, nuts, corn, grass, paper, or wheat. Grain size, odor control, and clumping are all important factors to consider before introducing your cat to a new litter. Older cats or cats who have been declawed will appreciate the soft, small grains you get from grass litter. Whereas a young kitten may benefit from larger grains that wood or walnut litter offers. Switching your cat’s litter can be a long process, but certainly a worthwhile one.
