You're not the only one with cat-drawing problems. ._. I've pretty much given up on drawing. I simply cannot draw cats, no matter how much I try. You're also not the only one with paw problems! x3
Fortunately, I'm not completely terrible at drawing the mouth. C: When I draw the mouth, it's often the second thing that I draw. After I've drawn the circle for the head, I draw a smaller circle for the muzzle. It should stick out a bit and overlap the bottom line of the head, but not too much. Then, lightly draw some lines to connect the bottom circle to the top.
Ack, I'll just make you a picture. I'm not good at explaining things.

It will look much better on paper, of course. I'd say I did good enough for five minutes... Cx
