Wildlife officials will remove as many as 200 feral cats that prey on seabirds and other critters on San Nicolas Island.
The project is expected to take as long as two years. It will involve using live traps, padded leg traps and tracking dogs to catch the non-native cats.
Jane Hendron, a spokeswoman for U.S. Fish & Wildlife office in Carlsbad, says healthy cats could go up for adoption, but those deemed sick will be euthanized.
Feral cats on the Navy-controlled island off the Southern California coast peaked in the 1950s. They descended from domestic cats that escaped from their owners or were brought in to hunt mice.
