Comparative Percentage Survival

This shows the percentage of rats still living at a certain age.

Lifespan by Location


Lifespan by Origin


It is very hard to compare like with like in this group. Shelter rats and rehomed rats are often homed at an older age than others, and with an estimated age, which will skew the data.

Lifespan by Gender


Lifespan by Ear Type



Contrary to some claims, dumbo rats do not have significantly longer lifespans than top eared rats.

Lifespan by Coat Type


Lifespan by Markings


Lifespan by Age Acquired


Lifespan by Year of Birth


The exceptionally long-lived rats are obviously not yetincluded in the figures for recent years.
