For a single mouse or a few mice...Put a gladlock or similar type container in the microwave and heat the water to where its very hot to the touch ( you DO NOT want the water scalding hot) then remove from microwave, place frozen rodent in the container of hot water, Allow to thaw until the rodent is "squishy" near the enclosure( should not take but around 8-10 mins). Use hemostats or tongs and grasp the rodent by skin on the nap of the neck , dab rodent on paper towel and present to the snake.*** You may have to reheat the water after thawing***
