「Mouse, rat」that「rescues」:「…the common terms rat and mouse are not taxonomically specific. Generally, when someone discovers a large muroid, its common name includes the term rat, while if it is small, the name includes the term mouse. …A 2011 controlled study found that rats are actively prosocial. They demonstrate altruistic behaviour to other rats in experiments, including freeing them from cages. When presented with readily available chocolate chips, test subjects would first free the caged rat, and then share the food. All female rats in the study displayed this behaviour, while 30% of the males did not.」

　「Norway rats, roof rats, and house mice are the rodents most commonly found living in close association with man. They are called commensal rodents, referring to the fact that they live at man's expense without giving anything in return. Rats have very high reproductive rates. A pair of rats and their offspring could produce 1,500 more rats in only one year if they all survived. Rats breed at 3 to 5 months of age, carry their young for 21 to 33 days and have 6 to 12 young per litter, and 4 to 7 litters per year. The actual figures within these ranges depend on the availability of food, the density of rats in an area and the age of the female rat. Although one female rat may produce up to 84 young in a year, on the average about 20 young per female per year survive to maturity. Female rats can breed again 1 to 2 days after giving birth. Breeding occurs all year…. Mice mature rapidly and by 1.5 to 2 months of age are old enough to reproduce.」

　「In Japan, it is not uncommon for mothers to sexually stimulate their children to soothe them so they will sleep. There have been stories in the press of mother-son incest arising from the strong nature of this relationship in Japan and the important maternal role of ensuring the son succeeds at school. According to Hideo Tokuoka, 'When Americans think of incest, they think of fathers and daughters. In Japan one thinks of mothers and sons' due to the extensive media coverage of mother-son incest there.」
