We ship all of our products frozen in insulated boxes with dry ice and ice packs. We limit our boxes to 35 lbs so that we can ensure that there is enough room to fit some dry ice and some ice packs in your order. Everything will be sent out frozen and tightly packed. If any of your products arrive partially thawed or starting to defrost, this is perfectly fine and safe! You do not need to worry or freak out. It is perfectly safe to thaw and re-freeze pet food.
