What is a "Normal" Cat?

Please click on the thumbnail images to make them larger.
So, just what is a normal cat? How could a student explain what normal is? Is it easier if you have numbers? Why or why not? What do you do with nonnumerical or categorical data? Can a cat have a mean (average) fur color? If not, how would you describe "normal" fur color. What kinds of charts or graphs would help? Is a sampling of 14 cats enough to represent all of the cats in the world? If not, how many should be sampled?
Is my cat's belly the most disgusting thing that you have ever seen?
Inquiring minds want to know!
