I swear that this is the first time I've ever seen an anime acknowledge that civets (specifically masked palm civets, called 白鼻心) are fairly common in Japan. Yay?

(I lived in Japan three years before I happened to spot a civet at night on a mountain road in Shikoku, and thought, "what the fuck is that?" People just told me, "oh, yeah, those are a thing." Until that moment I had genuinely thought I was thoroughly familiar with all the Japanese fauna. I somehow felt betrayed.)
