If you love cats and soon you are going to Hawaii, then surely include in the route a cat's shelter on the island Lanai (Lanai Cat Sanctuary). People from around the world seek to visit this island and, looking at photos, it is easy to understand — why. In a shelter there live 500 cats (495 if to be exact), and any visitor can stroke each of them if, of course, he has rather long holiday.
Lovely!
