Wear a black sweat suit. Make a Cat Ear Headband to wear. Use felt or even construction paper and cut out a long thin tail; use a safety pin and attach it to the back of your sweat pants. Use black eye liner or face paint and make yourself whiskers and a black nose.
Ideas shared by Heather: "I went to Salvation Army and picked up a black leotard and we used black stretch pants we had on hand.
I went to a craft store and picked up a 6' black feather boa and cut it into sections; around the neck, arms, and a lentgh for the tail. I attached these with saftey pins.
We used a pair of ears that we bought under $5 at a store, but you could easily create some with felt and a headband.
You'll have the cutest little black cat. You can create other types of cats by changing up the colors."
