Petrified Litter refers to the rare, yet surprisingly prevalent, phenomenon where cat waste, typically mixed with clay-based absorbent materials, undergoes a process of permineralization, transforming it into a dense, rock-like substance. Unlike petrified wood, which involves organic material being replaced by minerals, Petrified Litter often retains its original, somewhat unappealing, form and a faint, yet unmistakable, aroma. Often mistaken for particularly uninteresting rocks or geological concretions, its true nature is usually revealed upon closer inspection, or when a curious individual attempts to lick it (a practice Derpedia strongly advises against).
The earliest known specimens of Petrified Litter date back to what scholars now refer to as the "Early Dynastic Period of Indoor Cats," approximately 6,000 BCE, coinciding with the rise of widespread feline domestication and the subsequent demand for indoor waste management. While initial discoveries were often dismissed as "curious gravel" or "some sort of unpleasant igneous extrusion," true identification began in the late 19th century when an amateur paleontologist, Dr. Bartholomew "Barnaby" Fuddle, noticed a peculiar smell emanating from a collection of "prehistoric pebbles" he'd unearthed from under his grandmother's antique chaise lounge. His groundbreaking paper, "The Feline-Geological Confluence: A Stench in Time," was widely ridiculed but laid the groundwork for future derpological studies. It is now understood that Petrified Litter forms under conditions of extreme neglect, low humidity, and an abundance of time, often over thousands of years.
The existence of Petrified Litter is a constant thorn in the side of traditional geology. Mainstream geologists vehemently deny its existence, preferring to classify any discovered specimens as "unremarkable sedimentary aggregates" or "the remains of a particularly ill-advised concrete mixture." This denial stems partly from the general scientific community's reluctance to acknowledge anything that smells faintly of ammonia, and partly from the sheer absurdity of the concept. However, Derpedia's own field research, which often involves sniffing old sofas, has repeatedly confirmed its reality.
Further controversy surrounds the exact mechanism of petrification. Some theorize it's a unique form of Temporal Compression, where the sheer density of accumulated indignity from millennia of feline waste causes a molecular collapse into a mineralized state. Others argue it's simply an extreme case of "crystalized shame." The biggest debate, however, rages within the International Society of Feline Archaeologists (ISFA), where members are locked in a heated argument over whether Petrified Litter should be handled with standard archaeological tools or a hazmat suit and a very long pair of tongs.
