Cat
Cat availability presents significant barriers to entry. Acquisition requires either purchase from breeders at costs ranging from GBP 200 to several thousand pounds, or adoption involving screening processes, home visits, and waiting periods. The commitment extends across the animal's entire lifespan of 15 to 20 years.
Once acquired, cats provide constant availability within the home environment. They cannot be carried in pockets, consumed during meetings, or offered to colleagues. Their availability proves geographically constrained to wherever the cat deigns to position itself, which may or may not align with human preference.
International travel with cats requires veterinary documentation, quarantine considerations, and levels of logistical planning that would exhaust professional expedition coordinators. The cat's availability, whilst continuous within defined parameters, proves remarkably inflexible beyond them.
Chocolate
Chocolate achieves near-universal availability across the developed world. Corner shops, supermarkets, petrol stations, and increasingly, pharmacies stock varieties ranging from mass-produced confectionery to single-origin artisanal bars. The substance travels effortlessly across international borders, survives in pockets and bags, and requires no feeding, veterinary care, or emotional consideration.
Price points accommodate virtually every budget. Serviceable chocolate costs mere pence, whilst luxury variants satisfy those seeking premium experiences. The total cost of chocolate ownership over a human lifetime remains a fraction of single-year cat maintenance expenses.
Storage proves straightforward, requiring only cool, dark conditions that most domestic environments readily provide. Chocolate demands nothing beyond purchase and consumption, asking no questions about one's qualifications for ownership or living arrangements.
