All but one of the mice that I have fed Monty Joe didnt have a clue, but then why should they, they have never seen a snake. But I had one mouse that went face to face with my BP and it was a stand off. Then just as my BP struck, that dag gone mouse jumped straight up in the air. And this was the second miss that Monty had against this mouse. I swore that if Monty missed one more time that the 3 strike rule was in effect and the mouse would be spared and become the alpha male of the breeder mice. But I guess the third time is a charm because Monty didnt miss the third time. But he deffinetly had to work for that meal.
