Can the litter be composted or disposed of in a garden?

Dr. Elsey’s clumping clay litter is not biodegradable and should not be disposed of in the yard or garden whether it has been used or not.  Bacteria in cat’s waste can be harmful to other humans and animals.  The bacteria in the used litter can cause an illness known as toxoplasmosis that can be particularly harmful to pregnant women or infants if touched or handled.
