Sounds like thats been tried
Many ways to get it swapped over, such as...
Grasping the rat on its back with tongs and making it 'walk' around,
Tapping the snake gently on its side with the food,
Placing the snake and food in a tote overnight,
In a paper bag, folded and stapled, with small air holes, overnight,
Poking a hole in the rats head, to get some blood and brain scents exposed,
Dipping the food in chicken broth,
and combinations of the above.
The biggest key is patience.
And not to give up.
What doesn't work today, may work the next time
