Here are some other facts from the same magazine about the common brown rat.
1. Rodents have changed their preference from cereal-based foods to junk food
2. Brown rats can leap more than 2ft in the air
3. The Hebridean Isle of Canna recently had a rat population of 10,000. The human population on the same Island was 16. Rat catchers have now redressed the balance.
I am terrified of rats and have now decided never to visit the Isle of Canna, ever
