In the story of the game there's a part where another character recounts his backstory in a fairytale-like way, where he's depicted as a sad cat with matching CG. Scara-cat got really popular to the point where there's now official merchandise including a couple official plushies of him
Plus his personality is very catlike in general so he was already catboy-coded even before the actual cat showed up in the story
