Cat
The domestic cat represents a remarkably durable biological system. The species has survived five mass extinction events if one counts from the emergence of the broader felid lineage. Individual specimens routinely exceed a decade of functional operation, with documented cases reaching 30 years or more. The cat self-repairs minor damage, requires no replacement parts beyond food inputs, and maintains operational capacity throughout most of its lifespan.
Unlike manufactured products, the cat improves certain capabilities over time. Hunting efficiency peaks in middle age; territorial knowledge accumulates continuously. The cat degrades gracefully, typically maintaining core functionality until near end-of-life. No adhesive product can claim biological self-repair or experiential improvement over operational duration.
Duct Tape
Duct tape's durability, whilst impressive for an adhesive product, operates on fundamentally shorter timescales. Standard rolls maintain shelf stability for 2-3 years under appropriate storage conditions. Applied tape demonstrates variable durability depending on stress factors—UV radiation, moisture, temperature cycling, and mechanical load all accelerate degradation.
In protected applications, duct tape repairs have persisted for decades. The tape applied to seal a basement pipe in 1985 may well remain functional today. However, outdoor applications typically require replacement within 12-24 months. The tape cannot self-repair, cannot adapt to changing conditions, and cannot be restored once degraded.
