The majority of my BP's will happily take both live and f/t, I mostly feed live since I breed my own feeder rats but I don't produce enough to feed all my snakes and have to outreach within the local herp community for those exta feeders every week. Since most of us feed live we all tend to experience feeder shortages at the same time, this is where my f/t stock comes in handy. Also I generally feed my big girls f/t anyways because its been easier for me to acquire med/large rats frozen, not many people have them big enough often enough for me and the pet stores that do have them waaaaaaay overcharge.
