The pervasiveness of the indispensable litter box makes it difficult to imagine a time before cat litter. But in fact, cat litter is a relatively recent accoutrement to the feline lifestyle. In less than half a century, beginning with the late Ed Lowe--who "invented" the first commercial cat litter when he handed his cat-owning neighbor a bag of industrial absorbent--the cat-litter industry has burgeoned to a more than 700-million-dollar-a-year business in the United States alone. Given the volume of cat-litter products, it's not surprising that shopping for litter in the 1990's can be bewildering. There's a lot of it out there from which to choose. Sometimes, even when you think you've settled on a litter product, you find you have to switch for one reason or another. Your product-of-choice may mysteriously vanish without a trace from your local supermarket shelf, or a subtle change in the product's formula may cause your formerly "litter happy" feline to become displeased with the contents of his or her box. Don't automatically assume, though, your cat no longer likes its litter if it begins to urinate and/or defecate outside its box. Your pet may have a medical or behavioral problem unrelated to the litter. If you change products and your cat doesn't resume its normal litter-box routine, have you cat checked by your veterinarian. When seeking the ideal litter, remember, it must satisfy two demanding critics--you and your cat. Unfortunately, you and Fluffy don't always agree on what constitutes a "hit" litter. You both want an absorbent substance in which your feline companion will eliminate. And odor control is high on both of your lists. However, what smells good to you may not smell so good to your cat.
