Quick answer
Rats live in Cities, sewers, farms, riverbanks worldwide. Within that range they pick microhabitats that supply cover, food (Omnivore (highly opportunistic)), water, and breeding sites — and they disappear where those features are lost.
Key takeaway
Rats live in Cities, sewers, farms, riverbanks worldwide. Within that range they pick microhabitats that supply cover, food (Omnivore (highly opportunistic)), water, and breeding sites — and they disappear where those features are lost.
Rat native habitat
Rats (Rattus norvegicus) are tied to Cities, sewers, farms, riverbanks worldwide. Look for sites that match their diet (Omnivore (highly opportunistic)) and movement style; seasonal rains or prey shifts can expand or shrink local occupancy.
Microhabitats rats prefer
Cover for resting, access to food, and safe breeding sites decide day-to-day use. Edge habitats can help adaptable populations but fail specialists that need continuous wild land.
How people change Rat range
Farms, suburbs, and roads create opportunity for some individuals and lethal risk for others. Fragmentation without corridors isolates rat groups and raises local extinction risk.
Conservation geography for rats
Status in our guides: <strong>Least Concern</strong>. Protecting linked habitat often beats a single fenced reserve. Watch from a distance and never feed wild rats.
Diet and adaptability
As opportunistic omnivores, brown rats eat almost anything, from grain, fruit, and seeds to meat, refuse, and insects. This flexible diet, combined with rapid breeding and a tolerance for human environments, has made the brown rat one of the most successful mammals on the planet. A colony can grow quickly wherever food and shelter are available.
Range and history
The brown rat probably originated in northern China and Mongolia and spread worldwide by stowing away on ships and in cargo, reaching Europe in the 1700s. Today it is found on every continent except Antarctica, usually close to people. Its smaller relative, the black rat, was historically linked to the spread of plague, while the brown rat is the species most often seen in modern cities.
