In Mountain Lion, xhee

means 'snake' or 'python' (an imitation of a snake's hiss), xrrap
means 'blood' or 'liquid' (an imitation of slurping), plop
means 'drop' and (by extension) 'to give birth to', bow
means 'bad' (from a dog's bark), meow
can mean 'cat', 'no', or 'not', or it can even be a generic expression of sadness, and...see my thread on Mountain Lion for all the possible meanings of grrowrrr
