SHARK TANK - "Episode 208" -- A woman from Yardley, Pennsylvania could help cat lovers everywhere if the Sharks invest in her toilet training kit for cats, and the Sharks fight each other for a piece of a multi-million dollar company owned by a pharmacist from Palm Beach Gardens, Florida, who has invented a shoe with interchangeable tops. Also in this episode, an entrepreneur from Chicago is hoping to reposition her once successful designer line of maternity t-shirts; and an artist originally from Mexico City (now living in Chicago) and eager to make his American dream come true hopes the Sharks will want to invest in his line of extravagant yet affordable jewelry. In addition there will be a follow up from Season 1 on the father and son team behind Voyage Air Guitar and what happened to their business after turning down the Sharks' $1 million dollar offer, on the Season Finale of "Shark Tank," FRIDAY, MAY 13 (8:00-9:00 p.m., ET) on the ABC Television Network.
