San Francisco has a mice problem.
Technically the islands off of San Francisco coast do but in true city fashion, a plan to eradicate non-native mice has people upset.
The U.S. Fish and Wildlife Service is mulling over a plan to kill non-native house mice from the protected Farallon Islands off the coast of San Francisco.
The plan calls for officials to put rodenticide pellets on the islands to remove the mice because they are a threat to birds on the island.
Animal rights activists oppose the plan because they say the pellets will be ingested by other animals and spread through the food chain.
The islands are an animal refuge.
