Survey Introduction Page

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.
