How many takes on the old in-and-out are there? you ask. For 28 years the Pink Pussy Cat has been counting the ways, making it one of the oldest such stores in Miami-Dade County. Among the shop's impressive lineup of toys are ones that vibrate in every conceivable direction and others that buzz in a frenetic frenzy. At the apex is the five-inch-long, $100 Japanese-made Rabbit Pearl, which seems to move with a mind of its own. "All the products are tried out by the staff," says Anna, an extremely knowledgeable assistant manager. In fact the staff is one of the store's strong points. At one time Doris Wishman, a B-movie director and cult figure, worked behind the counter. Anna explains that about 85 percent of the store's clients are women. "We're very friendly, and we definitely make the customer feel comfortable." Men are most welcome, too, Anna adds. She says she often must reassure male customers that they are not obsolete. "Nothing can replace a man," she remarks.
