How Old Rats Live

How old rats live depends on genetics, living conditions, and diet. In general, rats can live up to three years if they are well-cared-for. However, many wild rats may not survive this long. They often suffer from drought and fluctuations in food supplies. So, how long can you expect your pet rat to live?

To estimate the average lifespan of a rat, the Ratty Corner compared lifespans for different species. It found that normal rats live around two to three years and dumbos live three to five years. The differences in average lifespans may be due to the genetic makeup of each species. Some rats are more susceptible to certain illnesses, while others are healthier and live longer.

A common question among biomedical researchers using rats is how old rats live. Few studies have attempted to answer this question. However, there are several ways to answer this question. One method is to correlate human age with rat life span, which is roughly equivalent to one rat month of life. Another method is to consider the different developmental phases of a rat’s life.

Rats reach sexual maturity around six weeks of age, or P42. At that age, they can start reproducing. Therefore, if you estimate their age incorrectly, you might end up with unplanned babies!
