How to make a cat scary ?

A cat, a very cute animal. Its a bit difficult to make it scary.... but it is not impossible.....

Cat of Diabolic

I simply play around with the color of the cat, of course, usually when we saw a black cat, with the eyes shinning in the night, which make the cat looks scary.
Well, as I mentioned earlier, cute also can transform into scary if we play around with all of the part.
In my digital drawing.. I put the cat in dark color with a bit red color, and red shinning eyes. Other than these, the teeth of an animal can actually show the animal whether it is friendly or not.
