• BY MELINDA GREENBERG WHEN MARTY C ELEBRATED HIS FOURTH birthday, his parents gave him a special comb. His younger brother was given a stuffed mouse so he wouldn't feel left out. Samantha received a pink and white fleece warmup suit before surgery and a hospital stay. Archie's aunt and uncle sent him gourmet popcorn and miniature bagels for Valentine's Day. While the occasions and the gifts were different, the recipients' responses were the same. They all wagged their tails. 52 STYLE Gone are the days when the only gifts for dogs and cats were rawhide chews and spools of yarn. Today, there are gourmet biscuits, videotapes, and even gold jewelry for Fido and Fluffy. Unusual pet products have become so popular, in fact, that recently Macy's opened the "Petigree Shop" in its New York Herald Square store. According to the New York-based American Pet Product Manufacturers Association, in 1990 pet owners spent $2 billion on their pets, for everything but food. (In 1989, $7.9 billion was spent on pet food.) Detroit pet owners were the first to test out a coupon book, "Pets and Their People," in spring 1991. Sold for $15 as a charity fund-raiser, the books offer about $5,000 in rebates on services and products for pets, as well as facts and trivia about pets. The Troy-based Entertain- ment Publications, Inc., which has also published books of entertainment coupons, entered into the pet market after their telemarketing research revealed that interest in pets was on the rise. "There was a need for us to service the pet industry," said Tricia Cecile, the account executive in charge of "Pets and Their People." "There is definitely increased interest and awareness in pet care." The coupon book will be distibuted in Columbus, Ohio, next year, and Entertainment Publications hopes to have it in other cities as well, Ms. Cecile said. While every dog may have his day, the '90s prom- ise to be the decade of the cat.
