I feed what works

Milksnakes I feed F/T mice if I don't have any on hand they eat whatever (not picky)

Pythons and Bullsnakes I feed live rats

Ball Pythons sometimes get F/T rats which usually is the result of having a surplus of rats during the winter.

In other words I feed a bit of everything but my preference is to feed live. (more convenient when you have over 50 snakes.)
