you dont have to worry about rodents biting your snakes either when you feed frozen. Ive been through the process of trying to convert a anaconda to a different type of food. My first green was stuck on chicks when I got her and now cookie will eat rabbits for a month and then refuse them for 6 and only eat rats. It tends to drive one crazy. If I could keep a conda on one food source I would. It makes life easier
