Stick with trying the frozen/thawed. If the snake doesn't eat this week, try again next week. Make sure you're preparing the rodent properly. Use your heat gun to see if the rodent is above 100 degrees.

Don't give in, don't feed the snake until it eats a frozen thrawed.

Now that's easier said than done and I've given in before too. But they will eat the F/T eventually.

Good Luck!
