This whole cat-take over thing reminds me of the Major from Hellsing. Thus, I drew him as a cat; a creepy cat, but a cat none-the-less. I got inspiration from this picture here: [link]
The Major wants nothing be war, and the pure chaos and destruction that comes from it - Much like a cat on catnip; which is why the title is sort of a play on a very long speech he gives where he asks his army (whom he refers to as 'gentlemen') if they want war, and he says, "Very well. Then krieg (war) is what you shall have."
I do not own Hellsing, Kouta Hirano does and he is epic. Likewise, I do not own cats because they are intelligent and independent animal.
