Sexing
You can tell the sex of your hamster by looking under
its rear end. Males are sexually mature around four
to five weeks of age and will have a lump where
the testicles are. It is normal for these to be quite
large in hamsters. Younger animals can be identi-
fied as male or female by the distance between the
anus and the genitalia. In females the two are close
together, while in males there is a noticeable gap.
