Another trick, take a hair dryer, on high, and blast the rats head for about 15 seconds, then offer immediately. This will get the temp up over 100, and seems to trigger a better strike reaction. If I don't get mine warm enough, my BP does the same thing. "Sniff, sniff, hmm... ", but if it's hot, it gets struck as soon as it is in range. Another great thing is that the hair dryer carues the smell of the rat to the snake ahead of time. Mine always comes out of the hide and gets into the strike pose when the hair dryer clicks on now.
