This 39-year-old has made millions toilet-training cats

Rebecca Rescate launched CitiKitty after she successfully toilet trained her cat in her New York City apartment. She created a product based on her method and to date has sold 300,000 units with more than $8 million in total revenues. When she launched in June of 2005 and priced Citkitty at $29.99, some of her family and friends doubted anyone would buy such a weird product.
