Indeed Tikkit, that is what is referred to as Fetish Hybridization Via Insertion Into a Setting.

Essentially Fetish A is inserted into a setting that is dedicated to Fetish B and thus becomes hybridized with Fetish B by virtue of being in the setting. In this case, the Siths are part of the Monster Girl Encyclopedia and are thus both Monster Girl and Furry, despite the fact that they distinctly furries and would not be classified as Monster Girls if they were separate from their current setting.
