Thanks to you fellow cats who weighed in on the question of whether the use of baking soda as an odor-controller in our litter boxes was good or bad. Steve checked with our vet, who said it was perfectly fine to mix in a little baking soda with my litter. Because this proved his female to be incorrect, Steve was naturally gloating. Not to be outdone, the female went on the Internet and found a Pet Place article stating that the ingestion of large amounts of baking soda could be bad for kitties. Not that I planned on eating large amounts of baking soda any time soon, but because females generally get their way with males (as is certainly the case in my household), there will be no more baking soda in my litter box. Sorry I don't have a more definitive answer, but I guess you'll just have to rely on your human (and your vet) to make the right decision.
