                          OIL-DRI COMPLETES ACQUISITION
              STRENGTHENING ITS POSITION AS THE WORLD'S LARGEST CAT
                               LITTER PRODUCER AND
              EXPANDING ITS ABILITY TO SERVICE CUSTOMERS WORLDWIDE


             CHICAGO - December 13, 2002 - Oil-Dri Corporation of America (NYSE:
             ODC) announced today that it has completed the acquisition of
             certain assets related to the Jonny Cat(R) brand of cat litter from
             A&M Products, a wholly-owned subsidiary of The Clorox Company
             (NYSE: CLX). Included in the purchase are trademarks, inventories,
             extensive mineral reserves and a manufacturing plant in Taft,
             Calif., located near Bakersfield.

             The acquired assets, which generate revenues of approximately
             $18,000,000, include Jonny Cat litter, Jonny Cat liners, industrial
             absorbents and agricultural carriers. The acquisition was
             structured as an asset purchase. It was made with internally
             generated cash and no additional financing will be required.

             Daniel S. Jaffee, President and Chief Executive Officer commented,
             "This acquisition is part of our strategic plan to expand
             distribution nationwide. Acquiring the Taft manufacturing facility
             ensures customers of quality service coast to coast. We see many
             opportunities to grow Jonny Cat while furthering distribution of
             our Cats Pride(R) brand and private label cat litter to markets
             where they are not currently represented. This facility will impact
             our distribution for agricultural and industrial products as well.

             "We believe there are at least 20 years of proven mineral reserves
             at the Taft location. As evidenced by the strong market share of
             Jonny Cat, these minerals are of the highest quality on the West
             Coast for cat litter, industrial and agricultural businesses."

             Jonny Cat is the most popular brand in several large metropolitan
             areas (including Los Angeles and San Francisco) in the Western and
             Eastern United States and Western Canada. With 75% of the business
             on the West Coast, this brand has years of proven stability and is
             considered a mainstay in the cat litter category.

             The top selling regional coarse cat litter, Jonny Cat is sold in
             several mass merchandiser and club stores including Costco, Pet
             Specialty, Petsmart, and Petco. Its primary distribution, however,
             is in the grocery market where 65% of the product is sold. The top
             grocery accounts include Safeway, Albertsons and Ralphs.

             "We are excited about being able to employ the staff at Taft, many
             of whom have 15 years or more of service at the plant," added
             Jaffee. "We are pleased with the seasoned workforce and the well
             maintained facility which should not require substantial capital
             investment to meet increased volume."

             Oil-Dri now operates 12 U.S. and international manufacturing
             facilities, eight of which are supported by mining operations. In
             business for over 60 years, the company serves diverse sorbent
             markets including pet products, industrial and automotive, fluids
             purification, animal health and nutrition, agricultural carriers
             and sports turf products. The wealth of Oil-Dri's experience in the
             mining and manufacturing sector will help make this transition
             smooth and seamless.

             "By utilizing our direct-to-customer delivery model and by
             introducing profitable line extensions we expect the acquired
             assets to materially enhance our cash return relative to our
             investments," continued Jaffee. "Once we have successfully
             integrated this facility into our manufacturing system, I am
             confident that it will deliver synergies that will make Oil-Dri
             stronger and more competitive in our markets and help us deliver
             value to our customers and our shareholders."
