My copperhead and my ballpython will strike at warmed wet f/t food. (The Pigmy rattle snake that I have will strike even cold food, thankfully).
I see it in the distinction between warmed food, that he has heated, and "cold" food, which, in my interpretation, is not just slightly heated. It is cold.
