Just use a good rat poison, give it a couple weeks to work though. Dont park your car out there till they are all dead or you will have dead mice/rats in your car. If you dont feed the cats as often they will definetly eat what they can catch, unless the field mice gang up on them, then you may not have to feed the cats. Usually when I poison rats in a barn I put some feed out for like a week or so, that way they get used to it and then you jut put the poison there instead of the food.

There are no stupid questions, but there are alot of stupid people out there that ask questions.
None of us are capable of screwing things up as bad as a group of us.
