Cat
Modern domestic cats achieve average lifespans of 15 to 20 years with indoor specimens, with documented cases exceeding thirty years. Throughout this period, core functionality remains largely intact, with age-related decline occurring gradually and predictably.
Importantly, cats do not become obsolete. A cat born in 2005 remains fully compatible with current household standards. No firmware updates render older cats non-functional. The interface between cat and human has remained stable for approximately ten thousand years, representing remarkable intergenerational compatibility.
Printer
Printer functional lifespan averages three to five years before mechanical failure or planned obsolescence renders devices unusable. Manufacturers discontinue driver support for older models, creating artificial death sentences for hardware that physically functions.
The concept of maintaining a printer for fifteen years provokes laughter in technical support departments. Replacement parts become unavailable within thirty-six months. Software compatibility erodes annually. A printer purchased today will likely serve as landfill by the decade's end, regardless of physical condition.
