City cats with green living owners will love this natural wheat-based cat litter. It looks like conventional litter and clumps in a similar way, but is totally flushable and biodegradable. Natural wheat enzymes work to control odors and it is designed for homes with multiple cats, so can cope with heavy use.

As wheat is a renewable resource, and this is made from non-food grade wheat without any added chemicals, this is a great green choice for cat owners. It also tracks far less dust than conventional clay litters. The only downside mentioned by one review was that bugs were attracted to the litter but this can be avoided by storing the unused litter in sealed containers, as you would any other wheat product.
