On the heels of a graphic redesign implemented last summer Libby Perszyk Kathman (Cincinnati OH) was called back to add a winter motif to package graphics. The result: all but three gravure-printed colors were dropped out "in order to optimize the consumers' creative potential" says a spokesperson for Newport KY-based Heinz Pet Products. The three-ply paper/film bag is provided by Union Camp (Wayne NJ). It has a water-based top coating that makes coloring easier. The 31/2-lb bag is the smallest 9-Lives offers. It was chosen so that it could be emptied in a relatively short time period allowing consumers to crack out the crayons. Two of the company's best selling varieties are being used for the promotion. The grand prize winner receives a trip to Chicago for a picture with spokescat Morris. The top three winners will see their entries on next winter's 9-Lives packaging.
