Ooh, I'm sorry. In my head, I was like "what if it's some old language and that's the correct transliteration? Nahhh."Except Cait Sith is literally how it's spelt in Scottish Gaelic. Unless you think they should've gone with Cait Sidhe, which would've led to a whole other argument (CATE SID-HE???) XD
Welp, it's definitely pronounced correctly, then! Haha
