Methodology to calculate the age of a mouse

There is actually no infallible mathematical formula to calculate the human age of a mouse because its growth and physiological changes during its life are very different from what's seen in humans.

However, it is rather based on the observations of the ages of the mouse, that veterinarians have established a correlation table (age chart) to see an equivalent in human age:

Real mouse age 1 mth 2 mths 4 mths 6 mths 8 mths 10 mths 1 yrs 2 yrs 3 yrs
Human age 14 20 26 34 42 50 58 70 100

Life expectancy of the mouse: The house mouse has a life expectancy of 2 to 3 years.

How do we call?
  • a baby mouse: a pup
  • a female mouse : a mouse
  • a male mouse : a mouse!

Animals rights

Animal abuse is unbearable, and it is important to give rights to animals. For more than three decades, the Animal Legal Defense Fund (ALDF) has been fighting to protect the lives and advance the interests of animals through the legal system, pushing government agencies to do their jobs to protect animals and shining a national spotlight on issues like factory farming and dissection in schools.
