Despite the scientific name brown rats originate from central Asia and northern China. They are possibly the most successful mammal on earth along with humans and can now be found on all continents except Antarctica. After reaching the UK sometime during the 18th century as stowaways on trading ships from Europe and Russia, it is now the UKs dominant rat.

Brown rats are incredibly adaptable animals and can take advantage of new situations. This has allowed them to be very successful in urban environments where there are opportunities for safe nesting habitat as well as numerous food sources from human created waste. In the UK there are very few predators that can take brown rats. Cats, foxes and owls may take young individuals, but fully-grown adults are unlikely to be predated. The greatest threat to an adult brown rat in the UK is road traffic and human rodent control.

The Guinness Book of World Records lists as the "fastest canine rat catcher" a bull-and-terrier dog named Billy, who killed 100 rats in 5 minutes 30 seconds (average of one rat every 3.3 seconds) at an event in 1825.[9] Guinness also credits Billy with having killed 4000 rats within a 17-hour period (average of one rat every 15.3 seconds) on an unspecified occasion;[9] other sources, including the 1993 edition of Atlas of Dog Breeds of the World, credit him with killing 2501 rats within a 7-hour period (average of one rat every 10 seconds).[10][11][12][13]
