came across the excellent ratty website
Rat Behavior and Biology, which
featured among other things a table comparing
rat and human ages.
The table only provided a general idea of how old my
boys were in "human years", but I wanted to know exacly. So I
created the rat age calculator, which in time has
become one of the more popular pages of this website.

age calculator. These are the main new/updated
- You can view and/or print a yearly
birthday calendar of
all your rats' "human birthdays".

you revisit the calculator later on.
- You can calculate the age of your rat not only as of today, but at any
- Your rat's name is included when you
link to the calculator
from your own website or blog.
- The calculator speaks Dutch as well as English. More languages could
be added in the future, if there's a serious demand.
If you have any questions or remarks about the
rat age calculator, then do let me know. My e-mail
