What are all of Rin's cats that have names? Of all the cats that have names, which cat is given which name (provide a picture or a description of its features)? How did Rin come up with these names?
Rin names her cats after famous people.

These are the ones I know of (collected from TVTropes, the Little Busters! Wiki, Wikipedia, and other sources):


Dorj (a nickname of Asashōryū Akinori):


Gates (Bill Gates): Unknown appearance.
Fabre (Jean-Henri Fabre): A rather chubby cat.
Einstein (Albert Einstein): Unknown appearance.
Lennon (John Lennon), on the right:


Tezuka (Osamu Tezuka): A shiny, blue (female) cat.
Schumacher (Michael Schumacher): Unknown appearance.
Hitler (Adolf Hitler): A spotted cat.
Audrey (Audrey Hepburn, I think): Unknown appearance.
Jackie (Jackie Chan): Unknown appearance.
Aristotle (no first name): Unknown appearance.
Isoroku (Isoroku Yamamoto): A small, grey kitten.
Cobain (Kurt Cobain): Unknown appearance.
Fedor (Fedor Emelianenko): Unknown appearance.
Hokusai (Katsushika Hokusai): Unknown appearance.
Yusaku, or Matsuda (Yusaku Matsuda): Unknown appearance.


However, you will notice how many are labelled "unknown" above; these are ones whose appearance I'm unsure of. These appear to be all of the cats she's named, but as she does not always name them directly or identify which one is which, determining their actual appearance is not always possible*.

* If I discover more appearances, I will add them upon discovery.
