I am the neighbhorhood/school cat, so I have a vocabulary of my own. It mostly consists of mrows, nmeuws and hggt!s. mrow:just kinda hey whassup I see you, nmeuw: hey! over here! and hggt!: hisssss! for the hggt, I would use hiss, but only snake hisses sound like hiss. and I couldnt find any better combinations of letters for it. I can purr! I honestly have NO idea how the hay I do it.
