First there is no systematic method that allows one to create the hierarchy (fig 2) on the basis of the table (fig1) (even after ignoring the top most and bottom most nodes which represent Universal and NULL respectively). If you know what that method is, please state it so that anyone can verify it. Try this, rename all objects and classes as consecutive letters. Then try to create the hierarchy. In particular, the links to mammal.

Second, you can't unclassify cartoon as a mammal in the table because it isn't being classified as an mammal. Both cartoon and mammal are classifications listed across the top. And as the author states "The elements on the left side are formal objects; the elements at the top are formal attributes [aka classes]; and the relation between them [objects and classes] is represented by the crosses." Please state THE square/cell (and there should be only one, if any at all, otherwise why the redundancy) to uncheck which unclassifies cartoon as a mammal without also unclassifying Garfield and Snoopy as cartoons? A portion of the table shown below:
