Editing Litter box (section)

===Non-clumping conventional litter===
The first commercially available cat litter in the United States was ''Kitty Litter'', available in 1947 and marketed by [[Ed Lowe (businessman)|Ed Lowe]]. This was the first large-scale use of [[clay]] (in the form of [[Fuller's earth]]) in litter boxes; previously [[sand]] was used. Clay litter is much more absorbent than sand and is manufactured into large grains or clumps of clay, making it less likely to be tracked from the litter box. The brand name ''Kitty Litter'' has become a [[genericized trademark]], used by many to denote any type of cat litter. Today, cat litter can be obtained at a variety of retail stores. Non-clumping cat litter is often made of [[zeolite]], [[diatomite]] and [[sepiolite]].<ref>{{cite web |title=Clumping cat litter Vs.
