Can you tell the difference between male and female cats?

People are very efficient at telling the difference between male and female human faces. What about other species though? We are interested in peoples ability to tell the gender of a domestic cat from its face alone. If you are interested in taking part in a short experiment then read on.

The experiment on this site is one of a number of experiments we are using to investigate this ability.

The experiment code is written in Java and so, depending on your machine it may take a while to load up. When it is all ready to go, you will see an image similar to the one below:
