From chapter 7 we know that Tonnura and Duke are brothers: The next chapter, though, implies that Duke may not be Tonnura's only sibling. Has it been revealed how many other siblings Tonnura has? And do we know anything about them (in particular, are they all large talking cats like Tonnura)?

The premise of Poyopoyo Kansatsu Nikki is that it's about a cat who is completely round. Does the series ever reveal why Poyo is so unusually shaped?

In a clip of Nichijou that I saw, Sakamoto the cat is seen being able to talk, and appears to be quite intelligent. (His lips never move, but he does speak.) How is Sakamoto able to do this? Are other cats able to as well?

At the very end of the first episode, Airi is shown saying "Whose eyes are those eyes?" - a key phrase from Chaos;Head, another visual novel and anime from the same creators. From what I've read, Robotics;Notes does have some ties to Chaos;Head that were seemingly cut from the anime completely (...

In episode 10 (Misaka Mikoto) Misaka 10032 finds a black cat. Touma tells her to choose a name for the cat, since she was the one who found it. She says that the cat will be called dog, which Touma dismisses, proposing that she chooses a "more majestic" name. So she says Tokugawa Ieyasu, which To...

In Sailor Moon, there are two cats, Luna and Artemis, who I believe act as advisers for Sailor Moon's mother, the queen. It's been a while since I've seen the anime, but were there any other sentient cats in Sailor Moon? Or were these two the only ones?

Often when users, mostly new (those who get association bonuses) ask a question, to identify it or its basis they will often create new tags and leave them as just that. For others of us who have no idea what this is, might want to help or are just interested it should be there. This also create...

The main character of Black Cat, Train Heartnet, is called Black Cat. Where did that name come from? Is it a reference to him being an assassin and, as such, being "bad luck" for people whose paths he crosses?

There are several similarities between the two characters and also the characters they interact with. They are both extremely skilled swordsmen. Their names/titles are slightly similiar and hint at being swordsmen, not entirely sure about Roronoa but Kenshin's name was derived from some samurai...

In Mashiroiro Symphony, Pannya is a cute cat-like creature. However, at least in the anime (unless I missed it), her actual species is not named. The anime also has plenty of ordinary cats, so it doesn't seem like Pannya is just a chibified version of a cat. Furthermore, there seem to be other an...

The first half of episode 9 of Tamayura: Hitotose is a short fable-like story, "The Melancholy of Momoneko-sama" ("Momoneko-sama no Yūutsu, na no de"). It follows Momoneko, the strange pink cat in the series, and his battle with a boar. Many anime fables are based on real Japanese legends. Is ...

Bakemonogatari episode 14 has a fairly famous tongue-twister in it, which Black Hanekawa recites with her cat voice. It was translated as: "Can you imagine an imaginary menagerie manager imagining managing an imaginary menagerie?". The scene is here (potentially NSFW): http://www.youtube.com/wat...
