How to draw a waving cat

Sketch the basic shapes
Lightly draw a round head, ears, a pear-shaped body, paws and tail. Add two crossing lines inside the head.
Draw the outline
Go over the edge of the ears, head, raised paw, body and tail. Keep the light lines for now.
Add the face and details
Draw the eyes on each side of the vertical line, level with the horizontal one. Add the nose, mouth, whiskers, cheeks, paw pads and tail stripes.
Clean up and add details
Erase the crossing lines and extra sketch marks. Add forehead stripes and a small circle inside each eye. Fill the ovals above the eyes black.
Colour the cat evenly
No shading yet: grey fur, cream face and belly, pink ears, cheeks and paw pads. Fill the eyes black, leaving small white dots.
Add soft shadows
Shade under the head and along the body. Leave the white spots in the eyes untouched.
