QUS 1; Lew lost her cat which she named Bangsal when she brought her cat in a playground located at Kuala Lumpur. She then posted a poster at Eleven Market near the playground to give reward to anyone who found her cat RM10,000. When Salman went to Eleven Market, he saw the poster. As he was walking to his house, he saw a white cat with the same leash and small bell as the photo at the Eleven Market. Salman brought the cat home and later contacted Lew to inform her that he had found her cat. They agreed to meet at a restaurant near to the playground on the same evening and Lew said she will give Salman RM10,000. Once she met with the cat, Lew only agreed to pay Salman RM2000. Salman was dissatisfied with Lew. Discuss whether there is a valid contract in this case. Support your discussion with case law and legal provisions.
