The title drew me into this story. I saw it and I was like, "Oh, I like zombies. And I like cats. Therefore, put the two of them together, and you have something double the greatness!" So I started reading this. Just thought I'd share. I really like your title, haha.
I liked the use of Danish words throughout this chapter. It's different than your average British student (though Ronan is British, as well, he just has a different background), and though I don't know whether they're accurate or not either (I'm not Danish either), I thought they showed a glimpse into his culture. I would just say that when using words from a different language, italicizing them makes it clear that they are from a different language. Sometimes I saw "Far" and my brain immediately went "a long, long way to run."
