Why are rats kept, what omens? - in detail
Rats are maintained for several practical and cultural reasons.
- Scientific research – laboratory strains provide consistent genetic models for studying disease mechanisms, drug efficacy, and toxicology. Their short life cycle and reproductive rate enable rapid data collection.
- Pet ownership – domesticated rats exhibit social behavior, intelligence, and low maintenance, making them suitable companions for individuals seeking small, interactive animals.
- Agricultural control – in some regions, rats are bred for training predators (e.g., birds of prey) to reduce pest populations, thereby protecting crops.
- Culinary use – certain cultures consider rat meat a source of protein, especially in areas where other livestock are scarce.
Cultural beliefs assign specific omens to the presence or behavior of rats.
- Prosperity indicator – in traditional Chinese folklore, a sudden increase in rat activity signals forthcoming wealth, as rats are associated with abundance and resourcefulness.
- Health warning – in European folklore, rats appearing inside a home during winter are interpreted as a sign of impending illness or poor sanitation.
- Death omen – some African and Caribbean traditions view a lone rat crossing one’s path as a forewarning of death or serious misfortune.
- Change herald – Native American stories sometimes describe rats as messengers of transformation, suggesting that their appearance precedes significant environmental or social shifts.
Understanding these motivations and superstitions helps explain why humans intentionally keep rats despite their reputation as pests. The practice balances utilitarian benefits with deep‑rooted symbolic meanings across diverse societies.
