FWIW, ????? sounds more like "first" than "fursuit." If you've watched Japanese anime (or listened to Japanese conversation in general), you might notice that the ubiquitous "desu" sounds more like "dess"--the "u" in the "su" is short and isn't very noticeable. "Fursuit" would need a long "u", i.e., ?????? (the actual word used is ??????, which sounds kinda like "fursuits").
