Draw a line on your eyelid starting from the inner corner of your eye and extending to the outer corner. Create a wing by drawing a small, slightly curved line extending out from the outer corner of your eye. Draw a line to connect the tip of the wing to the line on your eyelid. Color in the space between the two lines

Draw 3 to 5 whiskers on each side of your nose. A face paint pencil can also be used in place of eye liner.

Color in a V shape on your forehead to give your eyes depth. Shade your upper lip and bridge of the nose white to make your cat nose more prominent on your face. For an especially convincing cat look, draw a line from your nose that goes straight down and cleft it in two directions, leaving your lower lip to just do whatever you want with.

Gather a black headband, black foam, a hot glue gun, a pen, and scissors together Draw two diamonds on the foam. Make the diamonds 2 inches wide and 4 1/2 inches tall. Cut the two shapes out of the foam. Glue the center of the diamond shapes on the underside of the headband. They should be spaced a bit apart and glued where you want the ears to be. The short edge of the diamond will be attached to the headband with the long edges sticking out. Fold the long sections of the diamond up and glue the front to the back triangular piece on each ear.

Get fleece material in the length you want your tail and about four inches wide. Fold the material in half lengthwise with the right sides together and cut a rounded tip to the end of the tail. Glue or sew the edges together leaving the top edge open. Turn the fabric so the right sides are out. Stuff the tail with stuffing. You can use filler, newspaper, or other fabric for the stuffing. Glue or sew the top together and attach it to your shirt with safety pins.

Sew fabric claws onto gloves, and wear the gloves. Put fake nails on your nails, and file them into claws. Wear finger cuffs with claws on them.

A tight fitting, black body suit and knee high black boots will help you look like catwoman. Wearing leopard or cheetah prints with leather moccasins will give an animalistic look and add to the cat-like ambiance of the rest of your costume. Wear neutral tone colors with fur trim and fur lined boots to provide a general cat-like look

Cats meow when they are greeting someone, commanding something, objecting to something, or announcing something. When a cat purrs, it means that they are happy and content. A cat will hiss when it is annoyed, frightened, angry, or aggressive.

Get down on all fours and scoop in your abdomen to raise your back up. Cats arch when they are stretching after a long nap. Cats also arch when they are frightened. This is sometimes combined with a hiss.

Affectionately rub against people you like. Hiss and swat your hands towards people that are not respecting your costume.
