F/t, live, and p/k are all safe. All of these methods have their own risks associated with them. P/k means the animals already dead. So youre wrong in saying its the freshest. If you want to feed the FRESHEST, then live would be it. Youre right, you dont know how long the rodents have been frozen, thats why you buy f/t from someone you trust. Not trying to insult you, but the snake doesnt need a "fresh kill".
