It’s not often that an entrepreneur strikes gold twice in a lifetime. In this case, the gold was an appearance on ABC’s “Shark Tank,” a show that features business owners competing for investments from successful entrepreneurs.

Entrepreneur Rebecca Rescate, a 2002 Northeastern University graduate, was the first contestant in four seasons to appear twice on the show.
Rescate’s route from student to inventor of CitiKitty, a cat toilet-training kit, was more a matter of necessity than choice, she said. She couldn’t picture herself working for someone else. Although she learned business skills in her first post-graduate job at a New York City software company, she was “bored to tears,” she said.
