After complaints from the residents of Tatoosh about the number of cats on the island, the wildlife service carried out a relocation mission that saw the number of cats on the island drastically reduced. On the first relocation mission, 600 cats were relocated from the island to a neighboring island. On the second mission, half of the remaining cats were relocated to a rescue center inland. If the number of cats originally on the island was 1800, how many cats remained on the island after the rescue mission?
After the first mission, the number of cats remaining on the island was 1800-600 = <<1800-600=1200>>1200.
If half of the remaining cats on the island were relocated to a rescue center inland, the number of cats taken by the wildlife service on the second mission is 1200/2 = <<1200/2=600>>600 cats.
The number of cats remaining on the island is 1200-600 = <<1200-600=600>>600
