This is Methanethiol (CH3SH, Methyl Mercaptan), I created them in January 15th yet haven't posted about them yet until today. They are nonbinary and use they/them pronouns, as you can see, they wear a little scarf thing with the enby flag on it. They also have an egg on their head, as a reference as to how methanethiol is related to eggs. Also, their tail is based off a skunk tail. They don't like Methane (by Lily Irie) at all, since Methane tends to make fart jokes, and by logic, this affects them, and they just want friends, but they aren't too good at making friends, as not many people like them. They are also lightweight and fluffy, their best friend is Prymnesin-1 (I will post about them later). Their top scars are also somewhat triangular and they are the same color as their tail and ear stripes. They have a light brown patch around their left eye. When they get along with people, they are quite silly, like Bismuth-215. Also, they don't like cussing. Last thing, their ears are significantly lower than most cattos, which makes them look kinda goofy.
