My question involves a roommate in the State of: Georgia.

My brother, myself and his two friends just moved in a 4 bedroom, 3 bathroom log cabin in the mountains to finish out our degrees. One roommate brought in his g/f for a week, which has turned out to be about 3 weeks now. We just found out that she is "pregnant", yet she continue to drink, smoke and use tampons...Hence the quotes...Well the girl is not on the lease and has brought eight different dogs into the house. One puppy came down with parvo and it was put down, while the others are in and out of the house b/c she works at a vet and decides to keep every damn dog possible. Anyways, we told her she can't bring any other dogs into the house. They are never involved in cleaning the dishes or routine maintenance around the house and the dogs have chewed the insulation out of the a/c condenser downstairs, dug holes in the yard, and defacated everywhere. She also broke her window b/c she "got her hand stuck in an electric window"....Glass was found all over the driveway and inside her car. Anyways, enough of the drama. My questions are...1. Can we force them to move out if they are pregnant and it interferes with our way of life? 2. Is she responsible for utilities and rent if she's not on the lease? 3. Does anyone know of a hitman? Lol....Thank you for any help you can give me
