If you're an artist who likes drawing cats, (Like me) then you might want this short 8-step guide to drawing the cat eyes for your cat drawings/art. (Let me know if this helped!); 1: draw a sideways, somewhat L-shape.
2: Turn it into what looks like a rhombus. 3: Make the corners more round
4: Add thin, slit-like pupils.
5: Add more detail + shading and highlights; 6: Add line-art.
7: Color. I used green because I wanted too. 8: add final details. (Eyelid, eyelashes, more coloring, etc.
