When you sell/give away an animal, unless the receiving person signs a legally binding contract, you lose all rights to the animal. It sounds harsh, but it's the truth. When you sell/give away an animal, it's part of reality that it could wind up dead or it could have a great home. That's why it's the sellers responsibility to be thorough. Ask questions, even go to the future home. In the end, if you sell your baby rabbit to the first person who comes along, you really can't whine or complain if they use them for snake food.
