Cat
Annual cat maintenance costs in the United Kingdom average between 500 and 1,000 pounds, encompassing food, veterinary care, insurance, and the inevitable furniture replacement programme. This figure assumes no major medical events, a assumption cats frequently challenge through their enthusiasm for combat with neighbourhood rivals and exploratory consumption of dubious substances.
The cat, however, performs considerable self-maintenance. Grooming occupies up to 50% of waking hours, requiring no human intervention beyond occasional hairball management. The creature lubricates its own joints, sharpens its own tools, and disposes of its own waste with minimal supervision.
Segway
Segway maintenance begins with the purchase price of 4,000 to 8,000 pounds, a figure that causes physical pain to contemplate. Ongoing costs include battery replacement every three to five years at approximately 500 pounds, tyre replacement, and the occasional electronic component failure that renders the entire device inoperable.
Professional servicing proves essential, as the device's complexity exceeds typical consumer repair capabilities. The Segway performs no self-maintenance whatsoever, sitting inert between uses, silently depreciating whilst consuming no resources but also providing no companionship.
