KUCHING TRAVEL GUIDE AND TOURISM
Introduction To Kuching
It's safe and relatively clean. The name of the city, Kuching, is thought to derive from the Malay word kucing, meaning cat. Many of the locals refer to Kuching as the "Cat City" but it more likely comes from the Chinese word for port ("cochin") coupled with the Malay name mata kucing (cat's-eye) for the longan fruit, a popular trade item.
From verbal local history sources: "There was a small tributary of the Sarawak river called Sungei Kuching. It was from this stream that Kuching got its name. However, the stream has since been filled in and built over."
