Have you ever wondered how long a rat lives? In this article we will talk about the life expectancy of this rodent, both the one that lives in your home and the one that inhabits the sewers.

The lifespan of a rat can vary according to its species and habitat. Its passage through the wild is considered to be quite short. There are several exceptions, however, such as the twister rat, which can live up to 4 years with proper care.

The development of the rats

Just like their lifespan, the development of the rat is very rapid. When they are born, they are completely dependent on their mother, because they don’t have all their senses developed, such as sight and hearing, nor are they able to walk.

They only begin to see from the third week of life. And during this time, they learn to feed themselves much more independently, without needing a mother’s support.

Unlike a wild mouse, which becomes more independent at an early age, the house mouse is much more dependent and spends more time with its family.

From the age of 6 months, this rodent can already be considered a young adult. And at one year of age it reaches maturity and enters its final stage of life.
