Indeed! The classic cat eye is done with liquid eyeliner, which is notoriously hard to maneuver, so one of the quickest ways to make it easier on yourself is just to substitute pencil or gel liner. Urban Decay 24/7 Glide-On Eye Pencil is a great alternative to liquid liner because it's waterproof and stays in place extremely well, and we also like Chantecaille Gel Liner Pencil because it goes on extremely easily—perfect for keeping your lines straight. If you like how smoothly gel liner applies, you might also want to check out Bobbi Brown Long-Wear Gel Eyeliner; it has a finish similar to liquid liner, but it's much less of a hassle to apply.
Here's a technique tip, too: drawing a single line across the top of your lid only makes winged liner more difficult. Instead, draw your flick starting at the outer corner of your eye, then go back and draw the thin line across your lid.
