Clay litter create environmental problems both when is it strip-mined and then again when it is thrown away, since clay does not break down easily. The clumping agent in most (all?) clay litters is extremely harsh and is toxic if ingested in large quantities.
Alternative litters made of corn, wheat, paper or wood shavings are non-toxic and bio-degradeable. Many are flushable as well.
