Closing the cat incident :).
I drew a few versions of the last panel, and none of them convinced me that much. I think this one kind of works but it feels a bit at odds with the rest of the page. Anyway, there it is!
Credit: The 'prisoner cat' resolution via escaping through the window idea and drafts were made by a Ninja that pops around here sometimes. Truth be told, that version included also scenes of happiness with a mouse that was not actually dead and instead a very good friend of the cat but I omitted those because I prefer evil.
Update: Changed font.
