Step 10: Draw the rat's nose on the end of the arc guide. First lightly sketch a small circle. Then darken it using quick, short strokes for the fur. Draw a small line inside for the nostril.

Step 11: Use the initial arc as a guide to draw the rat's muzzle. Darken the top and bottom part of the arc. Inside the muzzle, draw long, quick strokes for the rat's whiskers.

Step 12: Use the arcs on the head as guides to draw the rat's ears. Darken the shape of the rat's ear and make the bottom part thinner. Draw some lines at the bottom and inside for structure and to indicate the opening. The ear on the other side should be thinner and facing away.

Step 13: Use the remaining lines as guides to draw the rest of the rat's head. Use quick, short strokes to represent fur and curve the lower right side up to draw the rat's jaw.

Step 14: Using the line as a guide, draw the rat's front feet. First draw the basic outline lightly to get the structure right. Then darken it using quick, short strokes to represent fur. Below the fur, draw the rat's paw using a series of curved lines for the digits. Only draw the three digits that are visible. Now draw the leg on the other side the same way, using the first one as a guide. Sketch lightly at first to get the structure right, then draw the quick, short strokes for the fur. Draw the digits below the fur.
