Below is an instruction that describes a task. Write a response that appropriately completes the request in Swahili. Please answer in Swahili.

### Instruction:
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?

### Response:
 Baada ya zoezi la kwanza, idadi ya paka waliosalia kwenye kisiwa ilikuwa 1800-600 = <<1800-600=1200>>1200.
Ikiwa nusu ya paka waliosalia kwenye kisiwa walihama kwenda kituo cha uokoaji ndani ya nchi, idadi ya paka waliochukuliwa na huduma ya wanyamapori katika zoezi la pili ni 1/2*1200 = 600 paka.
Ikiwa idadi ya paka kwenye kisiwa ilikuwa 1800, idadi ya sasa ya paka kwenye kisiwa ni 1800-600-600 = <<1800-600-600=600>>600.
