Feline acoustic output operates across a remarkable frequency range. The standard vocalisation repertoire includes sounds measured between 25 and 50 decibels under normal operational conditions, escalating to 65 decibels during feeding demands or territorial announcements. The purr, generated through laryngeal muscle oscillation, produces frequencies between 25 and 150 Hz at volumes that facilitate human sleep rather than disrupting it.

Noise generation proves highly context-dependent. Extended periods of silence occur during stalking behaviours and sleeping phases, which collectively consume 12 to 16 hours daily. Peak vocalisation typically coincides with the hours between 3:00 and 5:00 AM, a timing pattern that remains unexplained by current research.

The feline approach to floor coverage follows what researchers term 'selective territorial assertion'. Rather than systematic patrol patterns, cats position themselves at strategic chokepoints, blocking doorways, stairs, and corridors with precision that suggests advanced spatial awareness. A single cat can effectively control access to multiple rooms through strategic lounging.

Coverage patterns prove highly responsive to environmental factors. Sunny patches receive intensive occupation regardless of traffic requirements. Areas near food preparation zones experience heightened surveillance. The coverage, whilst incomplete by conventional metrics, demonstrates sophisticated prioritisation of high-value territory.

Cat maintenance requirements encompass feeding, litter management, veterinary care, and environmental enrichment, totalling an estimated 30 to 45 minutes of daily attention when properly executed. Annual veterinary costs average between 200 and 500 pounds depending on health status and regional pricing. Food expenditure adds 400 to 800 pounds yearly for quality nutrition.

The maintenance burden distributes unevenly, with intensive periods surrounding feeding times and litter attention, interspersed with extended autonomous operation requiring no human input. Cats maintain their own grooming protocols, eliminating bathing requirements that burden other domestic animals. The occasional hairball deposit represents the primary unsolicited maintenance event.

Cats navigate obstacles with a fluid grace that has inspired engineering attempts at biomimetic robotics, none of which have succeeded in replication. The feline skeleton contains 230 bones connected by joints permitting rotation angles that violate intuitive understanding of mammalian physiology. This structural advantage enables passage through spaces theoretically too small for the cat's mass.

Obstacle response demonstrates remarkable adaptability. Closed doors prompt immediate vocalisation campaigns. Novel objects trigger intensive investigation protocols. Other animals, including robot vacuums, receive responses ranging from studied indifference to tactical ambush, depending on variables humans have not successfully identified.

Feline territorial assertion represents the culmination of 10,000 years of coevolution with human domestic spaces. Cats claim territory through scent marking, strategic positioning, and unwavering psychological certainty of ownership. When a cat occupies a space, that space belongs to the cat regardless of any deeds, titles, or mortgage documents humans may produce.

This dominance extends to interactions with robot vacuums. Documentation confirms cats riding upon vacuum devices as mobile thrones, attacking devices perceived as territorial competitors, and training humans to deactivate devices through persistent complaint. The cat's territorial programming predates silicon-based competition by millennia and has proven entirely resistant to technological disruption.
