A process for manufacturing a moisture absorbent, moisture swellable particle. According to the process, calcium montmorillonite clay in powder form is processed through a cationic exchange reactor which provides intimate mix/shear forces to form an agglomerated particle. A soda ash (sodium carbonate) solution provides the exchange of calcium cations in the montmorillonite clay with the sodium cations in the soda ash solution to provide an aerated, agglomerated, moisture swellable calcium- sodium bentonite particle which includes a lower weight/volume ratio than the natural occurring mined sodium bentonite. As a result of the process of the present invention, the non- moisture swelling calcium montmorillonite is converted to a calcium-sodium montmorillonite which is highly moisture swellable and which possesses inherent odor control properties. An additional benefit of the present process is the capability of utilization of all of the raw material with little or no waste to produce a marketable odor controlling clumping litter product, and the ability to add a number of other odor controlling additives as powders which are intimately mixed into the litter particle for maximum efficacy, rather than added as discrete granules which would weaken the clump and which are less effective.
