These are shows that have cats as a main theme or cats show up very frequently in these anime.
These titles are about cute girls doing cute things! For the most part they have an all girls main cast. Only tv/web series added but you can be sure that any related specials to shows on this list would fit as well.
Planned watch order of the Aria anime.
All complete and incomplete series I own.
Incomplete: Inuyasha, Ranma 1/2, 08th ms team, Pokemon, Votoms, Niea Under 7
