content: Reminds me of when my friend moved into an apartment that was infested with mice and sometimes rats. He tried an exterminator and tried mousetraps but still had them running around his apartment at night. His co-worker lent him two of her cats. She brought them over in cat carriers and set them up with a litter box and food, and she told my friend to let them do their job. He said the cats hunted around his apartment all night and after a few nights he didn't have any mice or rats. Also said that when the cats were gone, the mice never came back.  Nature works against nature. There is a building near me that hired a man with a collie dog to chase geese off their lawns.
