Only twice? Man you've got to take some stronger stuff.

Seriously:

"Furry" is a slang term for an anthropomorphic animal, but there are disagreements over what exactly constitutes a "furry." Many proponents wish to establish an arbitrary dividing line separating furry from non-furry characters. Consensus is difficult when every enthusiast has their own criteria.

The difficulty is that most proponents insist on a digital representation, either "on" (furry), or "off" (not furry). However, observation of the genre quickly reveals that "furry" is analog, not digital. Every character can be interpreted on a furry scale, with some characters showing distinct furry traits, others with subtle attributes, and others with none at all.

The Chimeral Index provides a quick way to establish a character's "furriness." For convenience, the scale constitutes 10 Roe points, with 1 Roe being a mundane animal, and 10 Roe being a full human. Most "furry" characters fall within the range of 2 to 9 Roe points

Using the Chimeral Index classification system, we see that Jazz &c are Lagomorphs of about 34-42 stage points and a Roe value of 4 Devan &c are Podocnemorphs with 37 stage points and a Roe value of 4.
