Scampering through rats’ colorful history

Scampering through rats’ colorful history shares a disturbing factoid:

Rats are the ultimate survivor. Their life expectancy in the city is one year. In that time, a female rat can produce up to 12 litters of 20 rats. One pair of rats has the potential for 15,000 descendants in a year.

Rats versus baseball, baseball wins:

Rattus norvegicus, known as the Norway rat and the brown rat, arrived on ships around the time of the American Revolution. By the 19th century, rat fights were a popular form of entertainment. Dogs competed to kill the most rats. Having killed 100 rats in 5 minutes, 28 seconds, Jocko the Wonder Dog was said to hold the world’s record. Henry Bergh, the founder of the Society for the Prevention of Cruelty to Animals, shut down the rat pits, though some historians credit the rising popularity of baseball — a cheap alternative at the time — for the demise of rat fights.
