Diet & Feeding: In the wild, they’ll often feed on grains, seeds, nuts, fruits and vegetables
Social Behaviour: Rats commonly groom each other and sleep together. Rats are said to establish an order of hierarchy, so one rat will be dominant over another one
Males and females: Male rats are nearly always larger than females, often growing to as much as twice the size of a small female. Their fur will feel a little coarser and sometimes look a bit unkempt
Number of young: A female producing up to five litters a year. The gestation period is only 21 days, and litters usually number around 7
Interesting fact: Rats are very social and will take care of injured and sick rats in their group
